Running in Squares

The other day, I tried running again for the first time in about 2 days. I've been sick, you see, so I feel like a Zergling worked over with 12 Gauss rifles (=doubleungood). I got about 10 feet, and then my knees started hurting, and I had to stop. It's been a year since I've run. I just stood there and had a sudden wave of sadness, like when a Zealot is closing in on the last Marine. Blast away, man--there's no use. It's all futile. So we just have to dig in and try harder. Because who can stand up to a good Terran anyway?
