Live and learn

It was the labor day of the undead. Until the early evening, the campus had been eerily quiet, like something out of '28 days later'. Not a soul moved, except at Starbucks which was operating as normal. Now, finally, students were braving the outside, hoping the zombies had all left. Either that, or they'd just rolled out of bed. As I walked across campus, I spotted a figure on a skateboard heading towards me. Since the road he was going down was not on much of a gradient, he was slaloming across its whole width to keep momentum. 'Hmm' (I thought) 'that looks somewhat dangerous. Oh well, I guess you live and learn.' As the student came into clearer focus, however, I noticed his arm was in a plaster caste. So I guess, sometimes, you just don't.
