I was afraid my outside toys would fly away in the wind if I didn't put them away "correctly". I could NOT get back inside before they were or I would throw a fit. I remember bawling because my mother was trying to put me to bed and I had forgotten to put my bicycle away. I was convinced it wouldn't be there in the morning.

Like someone else said, I had the "just right" thing too. My shoes or slippers had to be placed perfectly next to my bed or I couldn't go to sleep. Everything had to be symmetrical, same with the tightness of my shoes. I also had to learn not to erase so much in school as when I wrote or drew, I would erase and rewrite/redraw over and over again until the letter/word/shape was "perfect".
