The thing that my W would never expect me to do is lay in a tanning bed. I have always (since we met in high school) told her that tanning was a waist of time and money, and not healthy. I learned to put up with it because W said it relaxed her, and made her feel good about herself. A month ago I found a coupon and said "what the hey" and went to a tanning salon. It was just as she said - relaxing and makes you feel good about your appearance.
I failed to complete the 180/GAL though. I have never told W what I did. I'm going to make it the triple crown - 180/GAL/mystery. I will "let her find" my tanning membership card and watch how she reacts. I can't wait!
