When I was still living at home, in my early 20's, EVERY TIME I went out with friends, I would come home to find my bedroom repainted or redecorated somehow, with the rock posters taken down. Then again, DM used to intercept my mail and throw away any fan club packets I would order (she and I have a better relationship now), so I went and got a post office box.
She cut a concert shirt into rags because of a word on the back, which was mostly starred out (it was Up All F&%)ing night (something like that) I never really wore the shirt, I kept it because it was my fave band. I had a band autograph my denim jacket, and she washed the autograph out.
Just a few years ago, I had a tank top that I had made saying Proud To Be A Canadian Redneck Girl, she destroyed that because she didn't like the word redneck! She actually emptied my suitcase from my Nashville trip that year and did my laundry for me.
I had a big mug that said BSers on it, and when we were packing her place for viewings to sell it, she accidentally on purpose dropped it on the tile floor. Didn't apologize, and when I asked what fell, she nonchalantly said just an old mug.
Anyhow, I could regale you with a lot of other stories, but that is what my mom used to be like. Sorry for the thread hijack! Please continue to post!
