Barking up the right tree

For the past week and a half, we've awakened to rain. Despite rain's promise to bring abundant, healthy foliage, rain has become drunk with power, a bully. It knows I want to stay in bed and sleep, and should I make it to my desk, I guzzle twice as much coffee as on a sunny day.

I feel awful. I'm mulling over a walk to the bank. From the bank, I could be tremendously lazy and get a cab by the train station, but I need the exercise. That's what's going to make me feel better, right? Lift me out of this achy funk?
