Because I have more of the urge to block things out and run away, I see myself as more of an autistic armadillo than a hedgehog. I still get mad though.
For some reason my brain wants to respond to this with a macabre and inappropriate sense of humor. Please ignore my brain, it’s an asshole sometimes.
That aside, an armadillo works pretty well. I mean, holy crap, they sure can sound cranky.
