"I don't normally drink," Aaron said quietly. "But thanks."

Actually, he never drank, under any normal circumstances....

Aaron sat up in his seat.

"You know," Aaron said as he drink some water from a bottle he had carried with him. "You keep yourself locked up in that book of yours a lot." 

Maybe it was the alcohol, but Aaron was just tired of being blown off. He couldn't try to move on from what had happened to him if all he could do was think. 

"Try out the real world sometime. It can be fun."
