Why does Monday come before Tuesday?

I am tired, but unable to sleep. It is too late for medication -- for then I won't be able to wake up fully to get the boys off to school. Perhaps a bit of writing will settle the fray and allow me to sleep.

I was thinking back over my life. Of the things that I have done that I don't understand now. Whatever the reasons were at the time, I made those choices. I guess it is like asking why does Monday come before Tuesday? That is just the way it is.
