I find it frustrating when people expect there to be a rational reason behind my compulsions. If it was rational it wouldn’t be OCD. I do it because my brain says so. And I pick my battles. If it isn’t something that gets in the way, I let it be. It doesn’t matter that I tap light switches or turn spoons down or change my socks several times a day or check the clock a hundred times a day (yes, literally). These things don’t impair my day to day function. So, I let them be. There is no point investing energy in fighting these compulsions when they cause no harm and don’t get in the way of anything.
