I just met a new, random brutha last week. Turns out, we have all kind of people in common that we know.

I'm going to a party this weekend / Yeah, I'll be there, too, cuz I know so-and-so.

I've got a friend that does what you do / Yeah, I know him too, we were hanging out last weekend.

What are the odds? I guess it really is a small world. Be careful what you say with folks you don't know - you might know them more than you thought you would. And they might know you, too. :-)
