What is one annoying thing that your mom does or did?

My mom constantly burps a lot! Now before you judge me, yes burping is normal and natural. My mom has excessive burping. She burps every minute and it's so ANNOYING! She makes this weird shape with her mouth when she burps. She goes "(BURPS) hmmm" every minute! It is annoying!! Ugh!!!!!!!! I can't even join peace and quiet with her because of it. I love hanging out with my mom and doing mother and daughter stuff. Burps quietly and says excuse me but at home she just burps out loud and doesn't say excuse me. Rude. She even burped in my ear a couple times when she was trying to do my hair. So fucking annoying! Lucky it was only two braids. I have to listen to music for now on when she does my hair. I can't take it!!!! My dad says there is nothing I can do and I'm just a selfish child who is being sensitive while my mom has a problem and I need to deal with it. How does it not bother him! It doesn't bother my brothers either. How am I selfish?!
