Most of my quirks are food related (I think)
I don't eat wet bread---dressing, bread pudding, soggy Italian beef, etc.
Pumpkin and custard pies are also a big NO because I don't like the feel of them on my tongue
I like cheese but not on sandwiches except for burgers
I used to have a lot of quirks about my house, everything had to be neat and in it's place.
My home was my sanctuary and I didn't like to have it invaded by anyone. After people would come and visit it always felt strange, like it wasn't "just mine" anymore. That might have come from growing up in a very small house with 7 other people.
Oh, I have a phobia about birds, heights and tight spaces.
