You know, I erred.
I do that once in a while.
In fact, I do it more often than not.
I was up in the middle of the night, because the cats were outdoors and causng a ruckus, as if they had cornered a coyote or something.
Half-asleep, I noticed the notation about asdf's birthday.
What I forgot to notice was that asdf's birthday is actually the next birthday, and it's not until March 19, the first day of spring.
Sorry about that, but one doesn't pay attention when one's half-awake.
