According to my wife, today's was the best. I made her a cd with a message from me and one song on it. I put it in her car cd player last night so she'd hear it this morning.
Unfortunately because she was distracted by the cd, she backed into the garbage cans at the end of the driveway this morning.

Now I have to rub out some scratches this weekend.
Worst gift would have to be nothing. Totally forgetting is not a good thing!
