1. I don't eat around people.
2. I can't drink any kind of drink, straw or no-lid, in the car.
3. Like I said in the "Irrational Fears" thread, I have knives hidden all around my room.
4. Most of my bookshelf is filled with hollowed out books that I haven't put anything in yet; I'm surprised nobody noticed it yet, seeing I have a Kindle and I have no need for books...
I'm sure there's more that I just can't think of yet. >.<
