a beautiful point is being made here. when a man and a woman love each other very much, and they decide to touch each other in a very special way, nine months later a stork brings them a little miracle, and they couldn't be happier.
then after the baby comes, the woman no longer wants to touch the man in a very special way. if the man tries to touch the woman, the love is rebuffed, often in a grand display. for, the woman's love has shifted to the baby, and nothing is left over over for the man. "I'm tired" she says. but what does she mean? the feeling is not sadness, the feeling is not joy - it is just nature's way.
In other news, how bout those Iranian babes? almost makes you wish you were there.
