How did Jimmy and Bob originally get to know each other in "After Twenty Years"?
When the policeman approaches Bob that night, Bob realizes that it might look a little strange to the police officer that he is standing outside of this closed hardware store. So, he launches into a story. He tells the officer that he is waiting for his friend, Jimmy Wells, a friend he hasn't seen in twenty years. He tells the officer,
"He and I were raised here in New York, just like two brothers together." (page one or paragraph seven)
Bob and Jimmy knew each other from childhood. They grew up in the same neighborhood and were very close since they were "like two brothers". When Bob was eighteen and Jimmy was twenty, they split up and went their separate ways, promising to meet again in twenty years at the same restaurant.
