I think I hate my grandmother.
Why do you hate your grandmother?
She never listens and she yells at me.
Your grandmother doesn't seem very nice. You're not required to like someone just because you're related, but you should probably do your best to remain polite when you have to be around her.
She is just an old lady with an attitude. She needs to be more of a human and less of an old stuck up bitch.
Hey, not everyone is likable. You don't have to like your family members.
