If parents are an issue, maybe instead of visiting anybody's parents for Thanksgiving, you guys can just go on a cruise! There's time to see parents when everyone isn't stressed out and trying to prepare a giant meal.
As someone who often chokes on my own spit because I'm super awkward and accident prone, I'm having trouble believing someone would do it on purpose, because it really sucks. Maybe he just inhaled too sharply before he was going to answer you. Either way, I hope you're able to work it out, and have a good Thanksgiving.
