I don't like my grandmother
I hope you're joking, who doesn't love their grandmother?
She is annoying and loud.
You should be nice to your grandma. She is just being herself.
Get off my back!
You seem to have some stress going on in your life, that is not good. Your grandmother is just who she is, you can't change her nor can you change yourself. We all have flaws and it is good to accept them as they are.
