I had a friend where it turned out that she hated my guts, all through our friendship. I thought she was my best friend, and then, in high school, she turned on me and had sordid affairs with all of the people that I'd dated. It was less hurtful because I was in high school, so it was more like, 'What's wrong with you? Gross!'
The actual, original 'Teenage Mutant Ninja Turtles,' I have vague memories of because I was pretty small, but I loved, loved, loved it. I have only those weird, visceral little-kid memories: I remember the extreme flat, two dimensional green that was their skin or the weird pizza with no sauce - it was just like yellow, drippy cheese.
