Things I never seem to be able to keep track of

...no matter how many of them I buy:
1. Scissors
2. Tape (scotch, packing, and duct tape)
3. Sunglasses (not helped by the fact that I seem to break pairs of sunglasses almost as fast as I buy them)
4. Ibuprofen and acetaminophen
5. Colored ballpoint pens
6. Socks
7. Gum
