I recently found myself in an incredibly awkward situation and I can't figure out what to do. I've asked all of my friends and we just can't come to any sort of consensus as to what the right move should be.

I was out at a bar a couple of weeks ago, catching up with some friends after work. I got up to go to the bathroom and spotted this dude I knew from way back; hadn't seen the guy in years, but I used to hang out with him and his wife quite a bit.
