The thing is, I don't want to imply anything about or judge Serendipity. He (can't image a woman for some reason) might be a very likable person with a kind spirit and a good heart etc. It's just his blindless for the obvious and the constant positive thinking and upbeat explanations that to me suggest that he has misplaced a marble or two in the upper chamber. The way he keeps on coming back has something of a person deeply involved in SM who just keeps on coming back for more and more punishment. Voluntarily.
If Serendipity had been on the Titanic, he would have been standing on the tip of the bow - the only part still above water - and he then would say "iceberg, what iceberg? There's a huge mass of something white in front of me that looks, smells, tastes and feels like an iceberg, but it could be very thick mist too. Besides, there might be a big airbubble left that lifts the ship straight again, who knows? I got a swimming degree, so I'll survive.
