Oh my god, that is so unlucky.
Its like when your in an argument and you realize the perfect thing to say...20 minutes after the argument has finished.
(Off topic - not so much embarrassing, just an example of one of the above) I was doing the lighting for an orchestra in a concert hall, and everyone was the except for one of the trombonists. Then there was some noise form the back of the hall.
As everyone turned round to see it, this trombonist - Ben - came out from underneath the curtain behind the rest of the orchestra, at the very front of the hall.
Only when he got sat down did I realize I had a spotlight pointed right at the place he came out. Grr
