"I hate it when things end up odd"
I do that as well. I tend to count letters in sentences to see if they add up to an amount divisible by four. I don't do this often, only when I'm bored and a sentence someone says sticks in my head. This seemed to start when I started taking typing in high school. But it never got disruptive or in the way of my life. That's where men came in! lol
These kinds of small tics are completely normal as long as they don't run your life.
Is getting onto FR and seeing what bizarre vanity TOH has posted considered a weird tic? Should I seek help? Freepers, you make the call.
Sometimes I find I cheat to get an even number though. I have a tendecy to break up contractions when it turns out to be an odd number. I'm pathetic, I know. I cheat on my compulsion. There must be a name for it..counter/even/odd/cheater.
