I fought the bed, and the bed won. No, it's probably not what you think. =]
Last night, I accidentally whacked my foot against the corner of my bed. After a moment of language that would make a Greek sailor proud, the pain went away and I went to sleep.
Waking up this morning, I find that I have bruised the bone that I hit (the metatarsal for my big toe). So, I get to hobble around the house and try to stay off of my foot for a few days.
If I can focus on something other than the throbbing in my foot, it gives me a reason to just concentrate on working on code.
