Just about everything that doesn't involve my work. Not that I'm mature then, just dealing with the clients.
One major thing, I guess, is that I CANNOT sleep with the closet door open. I don't get it, but I can't. I full well know that there is nothing alive in my closet, but if the door is open, I feel like something is staring at me waiting on me to go to sleep.
I still play imaginary games with my 6 year old daughter.. and I love the same games now that I did as a kid. I bought her Crossbows and Catapults the other day and sometimes want to play it more than she does. Also, I have been, and still am obsessed with games with miniatures. I keep trying to get my daughter to play Heroscape.. and she does, but eventually all of the time-travelling warriors end up as friends and go for tea together when she plays.
