I used to have all sorts of crazy things..
I had to make certain noises it was worst in about 6th or 7th grade.
I used to blink all of the time.
I have a few twitches mostly doing stuff with my neck muscles, or throat.
Nothing is bad or affects my life. The noises I made used to at times.
I don't like odd numbers, such as tv volume, but I can deal with it if I have to.
I used to open and close the right and left doors on my hotwheels cars the same number of times (matchbox actually, because mattel thought they were too cool to offer opening doors)
So my sister grabbed one from me one day, but it behind her back and opened and closed one of the doors about 20 times and wouldn't tell me which one. That cured me of that compulsion real quick.
