For my first entry I thought i'd start out with a little game...
you all remember "What Am I?" right?
so here goes....
I am black, although some of my brethren come in chrome or shinny steel.
I sit at the junction between solid and liquid
I pivot and move
I enjoy flying down the road, feeling the wind on my smooth surface and the firm, warm touch of my companion
I am strong though sometimes my existence has ended abruptly and I find myself laying in shattered ruin by the side of road
I am an essential (one could even say ÔÇ£pivotalÔÇØ) part of the whole
I am responsible for imparting forward momentum to the assemblage of which I belong
What Am I?
