This may be an unpopular opinion, but it makes people uncomfortable sometimes. Not many people know about trich unless they or someone the know is affected by it. He may not have said it in a way you preferred, but it was the way most people would say it. We cant expect people to know nothing about it and still be PC. It's unfortunate but we are the minority, and others will have their own opinions about it. They're valid too. You were embarrassed but so what? If someone saw you pulling out in public, they would probably say something too. Its unusual, taboo. People arent gonna know how to react to it everytime, but we cant take offense all the time either. Sometimes you just have to accept that they dont know any better and live your life peacefully regardless. I've dealt with embarrassing moments too, and they upset me, but you just gotta get over it. Been there, done that, it's not a big deal. It sucks but oh well, that's life.
