It’s hot here in Sacramento. I got lost wandering the UC-Davis campus looking for the Computers & Writing registration table. I discovered lots of bike paths — several of them more than once. I stumbled upon a building with people whom I recognize from various conferences. There was a nice snack table. I had helped myself and settled down with a plate before I realized I had walked into the tail end of a workshop session. What was I going to do, put the food back and leave? That would have been rude.
