I reach extremes...
Either really hyper, or really tired.
But it's usually the first...
I guess it depends on what's going on and how much caffeine is involved.
Some people know this better than others... since they've seen both reactions.
Once, I was extremely hyper, flying right out of my chair, and speaking gibberish, and, too bad for him, he was sitting right beside me... then the other time I fell asleep on him. He happened to be sitting next to me on both occasions, actually...
I wonder just how well he remembers this.
*Sigh...*
Good memories...
