My staff said I was cranky so I just left. Afternoon bike ride. I did need it. Sunny and 80 degrees AND a 20 mile an hour wind half the time in my face (I ride a long circular ride so whatever is going on is only bad half the time. Much of it was masochistic. Up hill into the wind. But I did need it, feel virtuous, and really like being able to just leave work when I want.
