We found a recipe for the ice cream on Recipe Source, and used his favorite Chai tea bags to flavor it.
He had some friends over on Sunday to celebrate. This is how a teen boy invites people over for his birthday: (Robbie on the phone) "Hey. Doing anything this afternoon? Wanna come over?" Mom: "Why don't you tell him it's your birthday?" Robbie: "I don't want to make a big deal about it."
They played Magic: the Gathering, Wizards (a new card game from Aunt Ellen), and TrackMania, a racing computer game.
Of course, they also made and ate ice cream.
