Strange o.O

I have this weird like, i don't know, mechanic in my head; like, whenever I go to post or enter something at school, it's always on an even time. like, okay, here's something; I would enter something either at the hour exactly, or at the half hour mark exactly. Sometimes it's even the same amount of minutes from a previous post, just with a different hour. And I don't even check the time before I hit send, so it's a sort of... weird coincedence? *ponders it*
