I like stepping on the cracks on the sidewalk but if one of my feet steps on more cracks than the other and the sidewalk ended or I'm leaving it, I have to go back and step on another crack with the foot I stepped on less cracks with to make it equal but then I have to step on another crack with my other foot because I didn't go back and step on a crack with that foot. So that entire process happens over and over again until I have to just deal with it. Man I hate my OCD
