Gents, I usually remember these things but must admit totally flubbing it this year.

Happy birthday, Mike, and happy birthday to you, too, Alex.

Mike, isn't your sister's birthday this month as well? (I've always had a hard time with name recall but I struggle now and feel terrible about not having her's in the frontal lobe where it deservedly should be. Dam and blast!) If so, happy birthday wishes wholeheartedly go to her as well.
