The inner workings of the male mind

I was thinking today (as I walked back to my office from my tip to the loo where I poked my eye about a bit in the mirror), there are so many people I know that the men (fathers) in their lives have just walked away in some shape or form. This could be litterally walking out of their lives, or by way of their choices, making them unavaliable for them.

So many people, so many ruined lives.
What is it with Men? Do they look at responsiblity and run away? Is it in their genes to be so pathetic? Is it infectious...? I hope not.
