1. I have this rock. I talk to my rock and take it everywhere. Did I mention that it's a rock?
2. I'll make up new, cat-themed lyrics to songs and sing them to my cats. I make Buddy dance with me while I do this.
3. I've developed the habit of smelling my beer before each sip, to enhance the tasting experience, and now that habit has spread to everything I drink. Doesn't matter if it's water or Diet Vanilla Coke or orange juice or whatever - I'm smelling it before each sip.
4. I brush my teeth, then rinse with this supposedly "cool mint" mouthwash that burns my mouth so much that I brush my teeth again right away to neutralize the mouthwash.
5. When I'm on the phone at home I can't just sit and talk. I have to either walk around or shoot pool or straighten things up - anything but just sit and talk.
