I used to be quite bad, but I find that as I get older I'm learning to stop myself but it's hard.
I like to count things, it used to be everything, like lines on a page, tiles on the floor. I blame count dracula from sesame street. but I've trained myself somewhat to stop now.
When I sat down to eat I used to have to touch the 4 corners of the table, in a particular order. But now theres a circular table so its all good.
Also I freak out if I realise I've been watching the TV and the volume was on an uneven number! eww, especially 17 or 19, why would someone do that?!
Finally, thankfully I've stopped, but after I said something I used to write the last word on the roof of my mouth with my tongue.
There's more, but I don't want to come off as complete insane now do I?!
