I intentionally spoiled game of thrones for someone who was being less than kind to me.
Did you actually do something like that? Before you spoiled it for her, did you have a reason behind it?
Yes, I didn't want to let other people be less than kind to me and get away with it.
She shouldn't have been rude to you, but an eye for an eye makes the world blind. Don't fight rude with rude.
She was sort of an idiot so I don't really care.
I believe you shouldn't call people names like that, or engage in revenge because it won't make you feel any better. How is she going to feel from all this name-calling? How about trying to apologize and make up?
