The sauna guy

So far countryside. I moved to a city and went swimming regularly in the biggest poolhouse, a little naive maybe, I responded to conversation in the sauna. It was a guy in his 50's or something. Well, he absolutely did NOT look nice - but that he would be after people like me just never occured to me. So what followed was a long series of his attempts to contact me (in that relax department) and that I became very suspicious about hanging there.
