Why am I up still?

I have no idea what the heck I'm doing up. In fact I should have gone to bed 2 hours ago but instead I washed the dishes and swept and mopped the floor, scrubbed the kitchen chairs and table, cleaned all the counters and the stove, scrubbed the microwave and the sinks. I must be crazy.
On the other hand, it does feel good to have it done. It needed it -- bad. It was probably the only time I would ever get it done. So why am I still up even though I am finished? Who knows.... maybe to wind down. Which is what you fine people are assisting me in doing by reading what I've written (you enablers you). So now you've wasted precious minutes of your life reading my inane babble when you could have been playing, working, spending time with your family, scuba diving, mountain climbing, writing a novel, inventing the next biggest thing since sliced bread, or saving the world from evil man-eating sheep who are striving to destroy us all one by one... you get the idea. Get back to work people.
I am going to bed. Goodnight.

p.s. The sheep thing is actually a real, produced and everything, cheesy horror flick. Don't waste any of your minutes on that either... I beg of you.
