My mom is so gross... she picks her nose, burps out loud without excusing herself, and always “hacks a loogie” where she’ll spit a ball of spit/mucus into the sink or trash can. She does many other things than the ones listed but these are the main things that bother me. I obviously can’t tell her to stop, because she’s my mom and I can’t control her. It’s embarrassing and disgusting..... am I wrong to feel this way?
