When my children were young, I told them that what would pass at home or among their friends would get them in trouble with teachers or could offend other families, so they needed to be fluent in two "languages," just as if it were English and Spanish. They got the message, became "bilingual," and were never in trouble.
On marrying a smoker:
My own dear, great-guy husband had a heart attack at 41, but smokes. He won't smoke in front of the kids, which is great, but instead his solution is to find a million and one reasons to leave the house so he can smoke: the car needs gas, going to go see if there are any good movies at the Redbox, going to take the pool water to be tested, need a bag of mulch, etc. Of course, these trips are never consolidated into one, they're always spaced out. Every time he does this he is choosing the smoking over his family, by (1) leaving us to go smoke, and (2) hastening his demise. (See: "heart attack at 41.")
I'm at the end of my patience with it all and wish I could talk to my twentysomething self. I'm pretty sure when the kids are gone I won't be far behind.
