Time biding in the library

Okay so I set myself up for 3 hours work in the library, get a moderate amount of work done, then pack up at 5.45 to go to the student food co-op meeting.

Next sequence of events were as follows; I arrive at the agreed location of the meeting. I see that the room is full of people with tiddlywinks. I sit down on a nearby step. I check the facebook event; the time says 3-4pm. I get up and leave. FAIL!
