I did notice it was David's birthday on Sunday. Also my Uncle Dobe's, unless that's next weekend. (My calendar is ambiguous on this point.) But I neglected to write either of them.
I did drop Cat a note for her birthday today, though. Happy birthday again, Cat! You're probably the only person I'm mentioning here who's likely to read this.
Later in the week, Ethan's birthday, followed by Tom Waits's.
I should send more birthday cards, or at least birthday greetings. Not to Tom Waits, though; he wouldn't know who I was.
