Yesterday I was pissed off all day long. I don't know why. At noon, my wife asked me "are you mad at something?" I had not even noticed how pissy I was until then. Everything bothered me. In the afternoon, I did hill intervals on the bike until I hurt sufficiently, went home and ate dinner. THen played video games until bed (I told my wife that I was gonna be antisocial), slept good and now I feel better.
