Please go away

Nan: *Getting Jamie's Halloween costume ready* Do you have a big belt with a big square buckle?
Mom: I don't. Jodey do you have a belt with a buckle?
Me: No
Mom: Do you have a big belt?
Me: No
Mom: Oh come on! You're so useless! Are you sure?
Me: Yes I'm sure
Mom: God you annoy me. Are you sure you don't have a big belt???
Me: Yes, mom! I'm sure!

Like can you please go away. I'm sorry, if I would have known in the future I would have gotten in trouble for not having a big belt, I would have gotten one!
Is there anything you won't get mad at me for?
