Balzac

I know this is completely mad, but I met a guy in Waterloo station this past Monday morning at Costa coffee. He sat down at my table and we started talking. It was curtailed when my friend came along. I had to go, but I am unable to stop thinking about him.

I am a Canadian woman and he is a Brit living in Brussels.
I know the chances of him seeing this are remote, but...

I am curious if this happens very often to other people?
