Do you moms or your children have any disgusting habits?

I'm 15 now. My older brothers have their disgusting habits of course, but sometimes I feel they learn it from my mom. I mean, gosh, she burps and farts right in front of us freely. Maybe I can excuse burping, but farting? c'mon.. and then she gets so annoyed at me, if I accidentally ped gas in front of her. sorry, for sounding weird, but that's just my household =l
