Post the completely pointless things you do that others may find strange/stupid. I say pointless because there should be no understood motivational reason behind your actions.
I'll go first, naturally.
I have a set way of eating chocolate squares. I'll eat half, suck half, and so on until there are 3 left. Then I'll eat one square and suck the last 2 dry.
Yeah, go on, come out the closet people, show your strangeness.
