I don't understand people who are afraid of mouses and rats. They are so cute. I would have caught the fellow and cuddled him
Mice amuse me; rats I tend to have a mutual respect with. I let the cats deal with both. That said, mice here are the primary vector of deer ticks in their nymph phase, and deer ticks carry lyme which is devastating to humans. So, I do go to some trouble to scatter poisoned mouse bedding around ("tick tubes"); this is harmless to the mice but kills the ticks. That's probably going to be part of my afternoon today, this needs to be done in April and Sept.
Now robins -- let me tell you, we have
insanely aggressive robins here, to the point that last spring I had one which would dive bomb me every time I went to get the lawnmower, and I carried a "robin stick" to keep him at bay. I have never seen such tiny, high-pitched animals being so indignantly violent before. They like to crash into the door and windows to the house at 5:30 AM, and my wife literally had to talk me out of walking outside with a gun at like 545 one day this week, because I was at the point of "I want to sleep and I am going to shoot every last one of you". I am glad she talked me down...
As for the topic here; I think shouting a lot inside a small enclosed space isn't very good, but corollary discharge interneurons prevent the sound of our own voice
as a general rule from causing us problems. Obviously this is a brain mechanism like anything else and so I'm sure it could be miswired or broken in some people. That said, I have spent a lot of time in the last 10 years screaming basically at the top of my lungs, either out of rage, or, more often, to make myself heard over small gasoline engines and pneumatic devices, and it's never caused
me any problems. We're all different, but this is one I'm not gonna worry about.
My wife yelling right in my ear when she doesn't like something about how I am driving, on the other hand....
