Trips are hard. There are hotels. Which may have bedbugs. At the very least, a zillion people have trod the carpet and touched the remote control, and who knows how often they wash the bedspreads.
And I flew on an airplane. In the heart of the cold and flu season. I didn't bring any hand sanitizer with me, and while I was tempted, I never did buy any, either.
Usually I don't really enjoy my vacations. This one, I did. Especially the last day. My feet, which had been hurting from bringing the wrong shoes, suddenly felt fine. The weather, which was forecast to be cloudy, was warm with brilliant sunshine. I looked down and saw a monarch butterfly, for goodness sake. While they're not rare where I was vacationing, I'd never seen one outside of 5th grade science class, so it really just felt like a magical day.
That's some positive conditioning for stretching my comfort zone.
