Hey, is that your old boyfriend from high school waving at your from the other end of the grocery aisle? It is! Go for it, wave him down, see how he’s doing.
Well you’ve done it, but now he’s making some strange faces, confused, looking at you and somehow through you. So you turn around… and there, behind you, stands his new girlfriend or wife or flavor of the month – y’know, someone who isn’t you.
Because of course he wasn’t waving to you. Of course he doesn’t truly notice you. Of course you made a fool out of yourself in public. And there’s no use in trying to play it off like you weren’t waving at him. You know it, he knows it, and his new beau knows it.
So grab a pint of Breyers and get the heck outta there.
