once upon a time...

A friend that I've known since college recently joined my project at work. I was trying to explain our relationship to a coworker who is only a couple years out of school.

The conversation went something like this:

me:	I've known him forever. Since college. We worked together on a project sophomore year.
coworker:	<blank look>
me:	I've known him for almost 13 years.
coworker:	Wow!!

I'm guessing that was something to the effect of "Wow, you're old."
