Happy birthday to my co-birthdayites!
Today is my birthday. It's also David H's birthday, and Jessica E's birthday, and Theo P's birthday, and Wendy B's birthday. Happy birthday to all!
In other news, according to Google I'm the only person to have used the term “co-birthdayites” on the web, although Bear and one other person have used “co-birthdayite” in the singular.
