They've grown up and moved on. Here's poet Thomas Lux's take on the tempus fugit nature of it all and the ability--or is it need--to let go:
A Little Tooth
Your baby grows a tooth, then two,
and four, and five, then she wants some meat
directly from the bone. It's all
over; she'll learn some words, she'll fall
in love with cretins, dolts, a sweet
talker on his way to jail. And you,
your wife, get old, flyblown, and rue
nothing. You did, you loved, your feet
are sore. It's dusk. Your daughter's tall.
