Also I'm half asleep.

I can tell this for two reasons. One is that I just pressed the wrong button on my trackball, but because I pressed it with the correct finger (i.e. the finger I usually use for the button I meant to press), I somehow expected it to do the right thing anyway.

The other is that I completely forgot to put that paragraph into my previous diary entry.

It's at times like this that I wish I could take the day off work simply because I judged myself too incompetent to get anything useful done…
