Dave Conrey talks about his circle of name-sharing friends:

We all went by nicknames because there are 2 guys named Chris, 2 guys named Sean and 2 guys named Dave.

I’m sure you can imagine what conversations were like…

“Hey Sean.”
“yeah?”
“No, the other Sean.”
“Oh, yeah?”
“Where’s Chris?”
“I thought he was outside.”
“No, the other Chris.”
“He’s hanging out with Dave.”
“which one?”
“he didn’t say.”
