I was tardy entering this thread, mainly because I knew most other people can make a right honorable fool of me at complex logic puzzles. But I just *had* to comment on this bit...

Why not? It seems to me that if you miss an appointment and you feel bad about it then there's nothing else to do *but* go home.

What *else* is he supposed to do? Barge into someone else's interview? Go out on the town drinking? Weep about it for hours to random passersby? Set a bomb on a bus in an act of vengeance, and program it to go off if the bus goes less than fifty miles per hour, just to be cruel? Is *this* the sort of psychologically unhealthy response to unfortunate events these so-called logic puzzles are meant to provoke? :)
