Babies make everything better

I was struck yesterday by how I've changed since becoming a parent.
Twice I was in line between a parent with a crying infant in a stroller, and both times I was filled with compassion and joy. Anyone, parent or not, can surmise why an infant cries, how they only have one form of communication, and forgive them (and the parent) of what can be perceived as a nuisance, but I'm certain that before I had a baby of my own, I never had such pleasant visceral reactions to such an unlikely distraction.
I've also found myself keen on the idea of having four children (though the wife would probably cap it at three), something I never would've appreciated as a bachelor.
huh.
