One Of These Days

It will happen to all of us. The thought of my name on one of those marble stones one day frightens me. I don't think it's death itself, just the process of of doing it. The older I get the more I think about that horrible day. I know I shouldn't think about it and that I should think more about enjoying the time I have on this planet. I do enjoy my life, but still, it's in the back of my mind. It's almost like knowing I have a bill to pay that is waiting for me on the table. I'm busy with work, kids, shopping etc, yet every once in a while the thought of that bill pops into my mind. Am I mad? Does everyone think like this?
