Happy Birthday!
Mac is another year older today. Since it's his birthday, you probably shouldn't comment on those new grey hairs.
This afternoon Mac is off for a very cute Dads and Daughters celebration with his friend Jay, who is off on paternity leave, and Jay's daughters Katie (3 1/2) and Kalisa (4 months) and, of course, Megan (1 yr).
Happy birthday, M!
