The boy child has gone back to college. This is as it should be. Luckily I sneaked in a little sniff of his head when he was on the sofa watching television - television which involved tall teenagers bouncing balls around and showing off their tattos while people with faces painted in various colors yelled and screamed. I pretended to be casually kissing him goodnight, since I go to bed at human hours and he goes to bed at bat hours. This head kiss feint is a common maternal behaviour. Why we like to smell their heads I do not know. I only know that when they are 3 months old you have to do it hour after hour since any babies I was related to preferred to be carried at all times when awake and to curl themselves around my head when they slept. When the babies turn 5 you get to do it pretty much whenever you want. As in, "Come here you!" However once they hit the teen years you need a strategy. I figure it's good for the aging brain. How to satisfy your craving for the creature that you gave birth to, without letting on.
I have a suspicion that he knows. But we are very High WASP about not discussing the matter. And BTW if I am so lucky as to have grandchildren, I will hold them and bounce them as much as my capacity to bounce by that time allows. But I am not planning to have them sleep curled around my head.
