The first great unknown line of April

It is not related to the month, so maybe the title of this post is misleading. So today a colleague on the continent asked me on Instant Messenger (technology is an amazing thing sometimes) asked me how I was. I answered: "Okay, but tired. I slept badly. Sleep eludes me, except during daytime." I don't know what was his reaction, but I thought it was funny enough to be a great unknown line. My first one blogged since the middle of March. It was about time.
