Everyone has deal-breakers and pet peeves in dating that they simply can't overlook. There are some are big ones like having different views on politics, kids, or monogamy, and others are small and petty like their second toe is larger than their first. We can't control what we like or don't like in another person, but we can definitely laugh at ourselves (and others) for our silly choices.
I broke up with a pretty hot girl when I was younger because she didn’t swing her arms when she walked. It just looked weird and reminded me of a gorilla. Really stupid reason I know, but it just looked so stupid and I couldn’t overcome it.
