"Oh really, who?"
"Well, he's the same age as my Dad, and he lives 3,000 miles away. We met through a group that we are both in."
"Turns out he KNEW my Dad, before I was even born, and I never even knew him!!! I found him before my DAD did!!! Weird, huh?"
"That's so cool!"
"Yeah, it is, and now we are really good friends! Six degrees of Facebook for you..." *laughing*
"I know, right?"
