I'm in a Philosophical mood, sorry, I get that way sometimes. What makes you wonder? I wonder about a lot of things and I was wondering what gets you thinking. Like why simple things are only simple when somebody else brings it up. Or, when someone invents something so obvious you wonder why the heck you didn't think about it. We have a lot of folks here from all walks of life. Lets hear what makes you scratch your head and go, "huh?"
