This is fun actually, remembering all the crazy things I've gotten.
My grandfather's wife (we had no contact with either of them and it was probably for the best) picked out presents for my sister and I, when they remembered we existed. One year we got Disney themed umbrellas, but toddler sized while we were 8-10ish. Another year we got matching barrette sets which were shaped like different kinds of bugs. I have an irrational fear of bugs, my mom has a full on phobia, and my sister doesn't much like them either. And it was my MOM's father. Those went straight into the donate pile.
My ex-BF's mother gave me a daily inspirational reading book. Highly religious of course. Wasn't offended, but also didn't read it and didn't keep it.
My friend doesn't give me inappropriate gifts, but she has a talent for getting things that I don't want. Purses, a book (which I already owned and was planning to get rid of), knitted scarves made of yarn I can't wear, etc.
