@dlowan,
Margo knows that this party had already been the victim of some misfortune.
We visited a friend of mine who is just home from hospital after major foot surgery.
She is confined to home for three months, and I was bringing her a good coffee, and some cigarettes.
(I managed to forget to bring her her birthday present).
I had just bought wrapping paper and sticky tape.
I left it at this friend's house...and didn't feel I could go back, because it wuld have meant her hobbling to her door to let us in again.
As I was checking one already wrapped present before I left, to see which was which, I heard an ominous cracking sound, so I had to throw an extra gift in, unwrapped, with the mixture of wrapped and unwrapped stuff (I didn't have time to get more paper, and do the wrapping). I had one too few gift cards.
