I've known this actor, Brad, since way back in Philadelphia in the days of the old Brick Playhouse, where my plays were first produced. He also showed up for at least one NYCPlaywrights meeting, back when we were meeting in person, but for the most part we're Facebook friends. So when I saw a guy sitting on the same subway bench as me on Sunday who looked like Brad, I naturally had to make sure it was the same guy - by posting on his Facebook page.
The best part is that as soon as I posted the message, he immediately began looking around for who it was who posted the message - which is when I took the photo.
Social media is a funny thing.
