Those little peg games at Cracker Barrel, the colors have to be symmetrical. I'll switch them out with an empty table if I have to to get the colors even. And don't even mention one of the pegs being broken and shorter than all the rest, I can't handle that at all. It has to be replaced or out of my sight. Its almost painful to look at. I feel like there is this little OCD monster inside me who comes out when I see those games. The worst part is my family knows it drives me crazy, so they try to mess up the pegs on purpose to annoy me. The really weird thing is that this is the only thing I am OCD about.
YES!! So much yes to this!!
If I can't make a pattern w/ the pegs, it pains me. And I have to set up the pattern before I play the game.
One year, as a gag gift, my parents got me one that had all white pegs.
My family would say I have a lot of quirks. I don't know if I do or not.
One thing I do, though, that a lot of our friends find quirky is that I have to dress us (DH, our 3 kids, & myself) in matching/coordinating outfits for all major holidays, vacation, & other important days/events. When we go on vacation, we have a week's worth of coordinating outfits.
I use antibacterial hand sanitizer A. LOT. When DH & I go walk at a local outdoor track, as soon as we get back in the car, I squirt some sanitizer on my hands. And DH is always like, "You literally touched nothing. I don't understand..." I don't know. My hands just feel like they have too much air residue on them or something.
We are a family of 5 - the 2 of us & our 3 children. I have to have things in sets of 3 or 5. If I get just 2 of something, it makes me feel like I'm leaving a child out - but, if there's a set of 2 things nearby the set of 3 things, it's okay because 2 represents DH & me, & 2 +3 = 5. For example, on our fireplace mantel, I have 2 candle holders on one side, &, on the hearth on the opposite side, I have 3 candle holders.
Those are just a few quirks. Admittedly, I probably have more...
EDITED TO ADD: Aaaand I just noticed you said "ONE" quirk! LOL!
