Same thing happened to me last year =[[ nice to know I'm loved, respected or seen as an adult.My relatives kept asking what year I was in high school then wouldn't believe me when I told them no I'm sophomore in college, then when I'd try to talk them they do that I'm talking to a child thing, act like they're being so patient letting me interrupt the adult conversation to say something.
on a separate note/tangent
I don't get why the fuck anyone would try to exclude their kids even if they were young. If you'd say "so they are out of the way so the adults can have a good time" that is such narcissistic BS. Kids behave better when they are included anyways because they aren't attention starved, then they also learn how to behave by being around adults thru observation. include your kids in your "adult conversation" let them think and learn if it something they don't understand, teach them. don't withhold knowledge because you can't be bothered to talk to your kids, or think they wouldn't be able to learn. idk I think it shows great irresponsibility to separate yourself from your kids like that, especially on what is supposed to be a family holiday. I understand, and recommend, taking a night out every once in a while but thats a very different situation.
