I want to be conscientious of etiquette but I don't want to get crazy... who is right, me or my mom?
My mom has 3 sisters. One of the sister has 3 children and two older stepchildren. The oldest stepchild has 2 children. The oldest is a girl who is 21 and in college. She speaks to me at family functions and I plan to give her a +1. The younger child is an 18 year old boy who is still in high school and lives at home. He never speaks to me and I doubt he even knows my name. Honestly, I don't really even want to invite him but I'm willing to do so. I am really against giving him a +1 but my mom thinks I should because he has a girlfriend. I read that anyone over 18 should get a +1. My larger concern is that this will open up +1 for any high schooler. To me this seems ridiculous. So... is it ok to just invite the family/household... 3 people?
Thanks,
M
