(It is Em's fourth birthday today. Partied out, the kids are sprawled in front of the TV, watching a documentary.)
CHARLOTTE: Hey Em, that man just said that a baby beluga stays with his mother for two years.
EMILY [excitedly]: I could do that!
CHARLOTTE (dispassionately): You did. In fact you get to stay with your mother for LONGER than two years.
EMILY (relieved): Whew -- good.
