Hanging out for dinner

AJ and Denisse were going to be meeting at the Pentagon City mall for dinner tonight, and they invited me to join them. I agreed. Since I normally leave work at 4 PM, I now get to stick around here until 7 PM when I am supposed to meet them. Still, I’m going to try and make good use of the time. How many pages of The Demon-Haunted World can I get through in 3 hours? (I’m currently 252 pages through the book.)
