You know your life has changed forever the first time he climbs out of the crib and scares the shit out of you by turning up in the kitchen. And, later, when he’s learned to drive and shows up unexpectedly, and you think, wait, how did you get here? Then, later still, when he’s taller than you and you’re hugging him goodbye one night near his college campus and someone walks by and says, “heh, heh, heh.” And you rush to call out, “no, no, he’s my son.” Don’t you see? He’s just my little boy.
