A year and a half later, Tammy - Cemantha's DeSales roommate - was getting married.
Bridesmaid Cemantha - who by then lived in Berwyn and taught children with autism at the Timothy School - needed a date for the wedding. While on Facebook, she messaged Bill to ask whether he was invited. "I'm going," he said. "I'll see you there."
Cemantha was visiting her sister Amanda in Florida when she sent the message. When she got home, she and Bill, a Philadelphia police officer, were again on Facebook, and, on a whim, she invited him to hang out.
He drove to her apartment, and, over a glass of wine, they caught up on each other's lives since 2004.
The September wedding was one big college reunion. And it turned out a group of their college friends had settled in Media. After the wedding, the whole gang started meeting for dinner or drinks there.
Bill and Cemantha, now both 30, also got together on their own. They watched many scary movies, ate a lot of hoagies, and played tennis. They were buds.
But in October, when Cemantha was Bill's guest at a family party, her nerves suggested something more was going on.
"I was going to meet his parents and his grandparents and his aunts," she said. "I was a nervous wreck!"
Shortly after the party, Bill told her, "I want to take you on a real date."
Arriving at Cemantha's apartment before she was ready, Bill plopped on the couch he'd been sitting on for months and turned on the TV.
After that dinner at Trattoria San Nicola in Paoli, the two continued mostly in their usual ways, with the addition of kisses and hand-holding.
By Thanksgiving, Cemantha had a question for Bill: "So, what's the deal? Are we a couple, boyfriend and girlfriend?"
"Yeah," Bill said. "I think so."
How does forever sound?
In fall 2010, Cemantha became an autism support teacher at Council Rock North High School in Newtown, Bucks County.
That winter, she and Bill spent New Year's Eve in Wildwood.
Bill had been looking at houses in Mayfair, and on their drive back to Pennsylvania, he told her he had made an offer. "If I buy a house, would you move in with me?" he asked.
Cemantha had lived with a boyfriend before, and it ended badly. She assured Bill she loved him wholeheartedly, but would never again live with someone without a very big commitment.
It wasn't long after that Amanda, who had moved back north, began pushing Cemantha into jewelry stores. Yes, she was on a mission from Bill.
In early July 2011, Cemantha and Bill were at her grandmother's house in Simpson to celebrate her brother Daniel's high school graduation.
"I was running around like a chicken with my head cut off, helping my mom make food and getting people drinks," Cemantha said. Then Bill walked up. "Would you go for a walk with me?" he asked. "I could use some air."
Before Cemantha could ask Bill to wait until she finished her host duties, Amanda stepped up to do them for her.
Bill and Cemantha walked across the street toward an open area with a gazebo, and, as they got closer, Cemantha saw candles flickering.
They stepped inside, and Bill got down on one knee. "Will you make me the luckiest man alive?" he asked. "Will you marry me?"
Cemantha said yes. When they hugged, she noticed her entire family was watching from grandmother's porch.
"Did you tell anybody about this?" she asked Bill.
"Just your sister," he said. Bill had asked her to bring everyone else outside.
It was so them
Bill's infamous love of pizza-flavored Goldfish crackers has led him to keep a bag of them at his place on the couch. Their 189 guests got a little cup of fish before taking their seats for the outdoor ceremony.
Cemantha wanted to make the big entrance that most brides make, but that took some doing on an open golf course. Her father drove the golf cart they arrived in, and she held a huge golf umbrella in front of her until it was time to walk down the aisle.
Bill has four godchildren, and each had a role in the wedding. Godson and nephew Andrew, now 3, was ring bearer. Andrew was born with club feet and has had a series of operations to fix them. He started walking just before the wedding, and seeing him walk down the aisle "was awesome," Bill said.
Andrew later showed he can run - during the ceremony, he delivered a cup of Goldfish to junior bridesmaid Lauren, another of Bill's godchildren.
The wind prevented the couple from lighting their unity candle until the bridesmaids and groomsmen made a circle around them.
With the help of family and friends, the couple DIY'd everything from their scratch-off-lottery inspired save-the-dates to the golf-tee-shaped place-card holders to the hand-painted polka-dot candle holders and table centerpieces.
This was unexpected
Bill knew the florist was going to personally hand Cemantha her wedding bouquet, so he made special arrangements. There was a Pandora charm bracelet wrapped around the stems.
Before the ceremony, the photographers brought the couple together to see each other for the first time that day.
One of the bridesmaids' blue shawls became a blindfold for Bill. As Cemantha got close enough to see him fidget, she thought, "Oh, my God, I'm getting married."
Bill said he never felt nervous until the bridal attendants started arriving at the ceremony site. "I just had that feeling in my stomach," he said. "But then Cemantha came up with that big, goofy golf umbrella in front of her, and everything settled down," he said. "Everything began, and it went great."
A bargain: The bride's veil, purchased off the sale rack at the Cove Bridal Dress Salon in Pennsauken for $25.
The splurge: Tammy does makeup professionally and did Cemantha's for the wedding. For the only time in her life she can remember, Cemantha did not look at the price tags at Sephora. "I could have had a heart attack at the cash register," she said. But now she has $200 worth of makeup "for special occasions."
