"Where have you been Charlie?," said Frank, a radio presenter.
"Try not to mock me when I tell you, I've been on an existential vacation," said Charlie, a dentist.
"Huh? Is that like where you go somewhere and ask yourself what it all means?"
"Basically, only I didn't really go anywhere, I just cleared my social schedule for a week, spent my free time thinking about 'what ifs' and stuff," said Charlie.
"Ah Charlie, not the 'what ifs' again," said Frank.
"Sorry man, they just crept up on me," said Charlie.
"Why do you always have to pull this stuff when everything's going fine? Everything's fine, right?"
"But that's how it is Frank, I only get that way when I'm not in a hurry, when I'm-"
"-on top of things."
"Yeah, on top of things."
"So you came to any conclusions on your 'urban retreat' or did you just go full circle?"
"Full circle, but that's alright, nothing wrong with reaffirming your life choices and-"
"Your life accidents."
"Yeah, that too," said Charlie.
"Just don't pull a Vonnegut."
"A what?"
"You know, a Kurt Vonnegut Jr., like when he'd get drunk and call up old girlfriends from something like 30 years ago and hang up when they answered."
"What about when someone else answered the phone? People move, Frank," said Charlie.
"Ah, well I suppose he'd have a conversation."
"What'd his wife think about this?"
"She kept quiet about it, anywayI don't think he ever knew he got caught, you didn't pull a Vonnegut did you?"
"Nah, that would be pathetic."
