I hate my mom when she eats.
Why would you hate your mom when she eats?
Because she has really disgusting table manners.
Even though you're disgusted by the way she eats it's terrible to hate your mother. Try to end these bad feelings about your mother.
Whatever, I'll just leave the table if she is going to embarrass me in front of my friends.
She's your mother, who brought you in this world. There is no excuse for hating on her over some small thing as her table manners. If you have any issues with her, just talk to her about them.
