One definition I heard of Insanity is to do the same thing over and over and expect a different outcome.
If this is true then I have an insane Red Cardinal roosting just outside of the house. He keeps flying face-first into the glass window – expecting a different outcome.

I suppose I could get some of those bird-shaped stickers for the window so he can see that there’s something in front of him, but it seems redundant since I’ve always got my curtains closed.

It would be funnier if he wasn’t waking me up in the morning. It’s as if he thinks he’s a rooster, but he doesn’t have the chops for it so he’s improvising.
