We all have things that we wonder about. I asked a girl one time as we watched birds hopping around on a lawn in front of us, "Why do you suppose they bob, bob, bob instead of walking? She thought a bit and said, "It's probably because they don't have butt cracks. It's probably hard to walk without one." The eight year old girl floored me. I never cease to be amazed at how differently some people perceive life compared to the way I do. I wanted to say that I have seen other birds walking...but I didn't. Sometimes I wonder how life can be so ugly but then when I think about moments like that and for a moment, I also think that sometimes it's a draw.hey im like that too igot four voices in my head when im trying to get to sleep three of them say sshhhh go to sleep but the fourth little bugger, he says I wonder if penguins have knees and off we go again lol
