I've got a lot more than one! How bout the top 5?
1. Sneaking out of work early to go home and workout. High guilt factor.
2. Dining out more than once a week: I'm getting up to 3x per week. High financial guilt factor.
3. Wine. I don't care if it's from France, Italy, Australia, Africa, California, New Zealand or anywhere else in the world. If it's good, I gotta try it.
4. Coffee. Ditto.
5. Reruns of Who's The Boss on Nick at Nite.
Sorry. I just couldn't stick to one. I have a lot of guilt!
