Are You a Doppelganger?

A guy named Neil Douglas was, I think, flying to Ireland on a Ryan Air flight and saw that there was somebody sitting in his seat. The person looked up and it was his doppelganger. And so they snapped a selfie and like posted it and everyone just went bonkers because these guys had no idea who the other one was. They weren't related, but they looked a lot like each other. It also depends on as far as whether you might look like someone about, you know, it just sort of makes sense if you look.
