Hah, I know what you mean. I never gave it much thought, but I do the same thing. I wouldn't worry about it. I have a lot of querks, and that's probably just one of your querks. I think I have more querks then your average person though.

Maybe I'm slightly above average girl!! Nevermind, inside joke.
I also have my favorite numbers like 7. I love seven!! Seven rocks!! It's awesome. Sorry. I don't know why I feel such love towards this number, but I do. Then I always considered 3 and 6 to be my "lucky" numbers, but that was only because they were actually related to good things. Another number that I like pretty good is 4. It isn't like I like to have 4 pieces of jolly ranchers, or 7 skittles, but I just like to think about those numbers. I like to see them. I don't know why!! lol It's just odd. I'm glad I'm not the only one with odd number related querks...or whatever it is.
