It's ridiculous, the things that can make you feel better sometimes.
Yesterday afternoon I stumbled back up the hill to work after a particularly grueling therapy session, red-eyed and sniffling. Coworker Ken, who had arrived while I was gone, looked up from his computer at the front desk and I swear his face just lit up, and he said, "Oh! I thought I wouldn't see you today! It always makes me sad when I get in and your office door is closed."
Thanks, Ken. That just made my day.
