I know you...

Ronny, my ex with whom I am still friends and currently roommates, switched to the Gold's Gym next to where he works, which is walking distance from where we live. Some Brazilian guy asked him something the other day (like "you using that machine?" kind of stuff) and Ronny recognized him from pics he had seen on my computer.
"Are you Brazilian?"
"Yes"
"From Bahia?"
"Yes"
"Are you Sergio?"
"...yea..."
He lives a couple blocks in the other direction. Didn't ask Ronny who he was. I assume he figured it out after Ronny mentioning he moved here from Worcester.

And of course Ronny's comment to me was, he's looking old - and he's getting fat!
Aren't friends great!
