There's nothing much very strange about me at all (although people who don't know me as well as think they do might disagree - but that's because when people don't understand someone/something some have a tendency to "fill in the blanks" when it comes to the stuff they can't/don't see or understand. Anyway, I'm about as "non-strange" as they make 'em. I have plenty of small quirks, I guess; but only three really come to mind as "main ones". One is that I "visually prefer" to have things placed at right angles. A few items on a table, for example, will look less messy if they're at right angles, rather than just thrown down willy-nilly. It doesn't reach the level of OCD, by any means; but if there's a gracious, socially acceptable, way for me move things and make myself just that little bit more at peace with how neat things look, I'll do it. I'm not above straightening up piles of things like brochures at the ATM machine either (as long as I'm standing there anyway).
The second one is that I don't drink the last bit of anything in a cup or glass. I guess I figure any little bits of objectionable stuff might have settled at the bottom. (We all know how coffee grounds and tea works when it comes to that, but I don't assume there aren't other things that could have gotten into the drink.
Third one: If I eat a slice of pizza or pie the point has to be pointing toward the left. The left because a) I most often use my left hand for a fork (oh, a fourth quirk - I only eat pizza with utensils (too inelegant otherwise), but also the left because the left is a side direction. I don't like food (especially indulgent food) pointing at me. Well, I don't like anything that seems at all, and even in some silly way (which isn't even really a "way" at all), to be calling attention to me
Mine aren't really "fun" quirks - just kind of "slightly peculiar" things.
