Answer: Starting now: Stay home when you feel sick, don't let your fights spill over into other people's time, and don't try to manage people's impressions of you. Your behavior has to speak for itself.
I've kind of buried the middle one, but it's huge. A "major beef" over a forgotten piece of information? Really? And it spilled over into the evening? Any negative impression you made on witnesses is accurate, I'm afraid.
Fuming has no place when something has gone wrong by accident; save it for when people do harm with intent. It also has no place at an occasion you're sharing with others. Either step away and resolve the problem quickly, agree to talk about it later and shake off your foul mood, or excuse yourself graciously and go home.
This self-control is a courtesy for others, but exercise it mainly for your own sake.
This might not apply here, but so often does: If your "major beef" was a flare-up of a recurring argument, please also resolve to declare peace, even if it's just a sustainable agreement to disagree. If you can't do that, then consider ending the relationship.
Recurring fights don't fall under the "All relationships are work" umbrella so often used to shield them. Instead, they're like jealousy: symptoms of something serious. Re-arguing the same old stuff says you two aren't mature enough to either settle your differences or part ways.
Q: We are planning a tiny, no-frills wedding ceremony next month and, a few weeks later, a casual party for friends/family. We are fully independent and happy with the state of our material possessions.
Still, I suspect that not having a gift registry will seem odd to certain members of my family and their social circle. Can we say anything to dispel any worst assumptions - i.e., that this is an unstated "cash only, please" request?
A: No, that will only make it worse. Just be your natural, non-greedy selves and that will suffice for those whose affection for you is paramount. Those who relish finding things to complain about will do so no matter how you try to pre-empt them. The less you say on the topic, the less can be used against you.
