What do you think about me throwing away my girlfriend's insane amount of grocery bags?
Why do you want to throw away a bunch of grocery bags?
She asks me to help with the groceries and the bags are piling up
Do not concern yourself with something that is so petty. It is wrong of you to throw away items that belong to someone else.
I live here too and I don't want the bags to spoil the house.
You should speak with her about it instead of just throwing them away, because she may want or need them and you should respect that. Would you want her to throw away something that you care about?
