i cant step on cracks when im walking outside so if i do step on one i have to step over a crack any one as long as its outside and a clean crack with each foot 8 ×8 times if i cant do it outside my backup compulsion is to find a place inside where the floor is segmented and do it there but if people are watching i have to find a wood surface to knock on 7 by 7 times the numbers are always more too because i lose count or feel like its not enough its exhausting
