The Longest Day

I've had a long day.

My day started with my mother-in-law thinking she had either a stroke or a heart attack (she's fine), continued with me trying desperately to create a presentation on a subject I don't understand, and which I have to present to one of our customers tomorrow, and ended with me teaching first graders, while one of them was giving me some serious lip, and doing whatever he wants.

Now I am dreading the aforementioned presentation, as I still have no idea what I'm talking about.

Joy.
