Prerogative of being middle-aged and single with no dependents (human or otherwise): after discussing the idea for 30 seconds with a friend at dinner, I just decided to have a long weekend in New York in about three weeks. I will visit friends, buy books, and see this. I got a great deal on a room in a very nice hotel centrally located between two subway lines. From decision to execution took all of 30 minutes.
Another prerogative: I can change my mind just as easily as I made the decision in the first place, with no repercussions or arguments whatsoever.
La vie c’est bon!
