I've told her politely that she doesn't need to buy me stuff and that she should just save it for Christmas, but she won't listen.
I don't want to hurt her feelings, but I don't want her to waste her money (she is not wealthy) on stuff I really don't like or need. It's starting to make me uncomfortable.
Oh, you poor little shit. Your biggest problem is your Mom likes to do nice things for you? You should be so lucky. Some Mom's raise (or don't) latchkey kids, or they drink a lot, or hit their children. Your Mom is so lonely that she thinks of you constantly, and this is one way of showing that. And the fact that she isn't wealthy shows that she would gladly spend her money to make you happy so you can look good at the sorority get-down or bar crawl, or whatever your ungrateful ass does. If I was your Mom i would send you anthrax in an H&M box. Then you could truly separate nice surprises in the mail to a quarantined room at Good Shepard. You are going to make such a bitchy wife.
