I hit 40 and was still waiting
I think I got old when I got a baby then I got young again. I'm old enough to know better and young enough to do it anyway and I do!

I read a sad story back when, shit I can't remember the country, sod it. European, repressive regime toppled, state run nursery's full of babies. When the humanitarians went into the nursery they found all these hundreds of babies who were clean and well fed but the children did not smile or respond to people and they reasoned that they'd never learned to. They'd never been nursed and cuddled and hugged and talked to so they hadn't learned to socialize and respond at all and there seemed to be some concern that they never would because of missing out on such important things so young. Children are a sponge and if they don't get filled with some of the good things then we make little monsters.

How many people do you know who hold a grudge and think that by doing so they are hurting the one they have the grudge against. It is seldom so. They simply hurt themselves. :D
