My kids go one better. "Hey Bet and Aleph, how old are you today?"
And now, because I love you so much (and for a limited time only) I bring you a blast from Year One, or as Aleph and Bet like to call it, "Laughing Babies." Note: that's Mary Poppins talking, not me. My line doesn't come up till the middle of this video:
"Best. movie. ever."
[sorry. all gone!]
