A few years ago we had a couple of feet of snow in a day. As I was snow blowing the driveway, I noticed all these little tunnels on the edge that was cut off by the side of the blower.
Then I saw a tiny little animal. I thought he was a mole. So I took my glove off and picked him up, as a good hillbilly would do.
That thing bit me like fifteen times up my thumb before I could react to yeet him across the yard.
Lesson learned.
That's not evidence of being mean but alive and interested in staying that way.
I had a similar experience with a common squirrel that found its way into a friend's kitchen. It's a story about a stupid human treating a wild animal as his pet cat and getting holes in his hand in the process, not how squirrels are mean.
Wish it hadn't found a way into the house, as I would have liked to have it keep clearing pests out of my yard. It got dropped off else where quickly, after a snack.
There is a reason that unpleasant women are called shrews[1], for example as in The Taming of the Shrew[2].
