On Thursday night I went to the party. The invitation from Helen arrived on Monday, but I did not decide to go until the last minute. I do not like social meetings very much. It was a farewell party for two Spanish artists who had been working on an art project at the Holmesburg Prison during the summer. I didn't know them and probably I wouldn't know any other guests either. In fact, I didn't know anyone except Helen. Maybe that was the reason I went to that party.
