You won't even notice.

No, really.  You won't.

Because we've never interacted.  I know who you are, you know who I am, we went to the same elementary, middle and high school.  But we've never been friends, never shared a class, never been on the same team, never performed in a group, never competed against each other.  I remember that you once had an unsightly wart on your nose, that at some point was removed.  You probably remember me a skinny and snaggle-toothed.  Which at some point changed as well.

Not really anywhere to go from there, so... goodbye!
