Crush! Kill! Destroy!
I am a peaceful soul. I usher wasps back outside. I let spiders and snakes live. When we first moved onto this property, I went to check the barn. A slight motion out of the corner of one eye resolved into a humongous rat on a rafter above the aisle. Panning back revealed an equally impressive snake looped back & forth over the other end of the rafter. I shut off the light, backed out of the barn, & left them to resolve their differences. Never saw either one of them again.
The exceptions to this detente are all bug-related, particularly horse flies, deer flies, enormous armored black bugs, and their ilk. Threaten to bite one of my horses? Strike fast, strike hard, and finish by stomping the carcass into the ground in case it was only stunned. Sanctity of life? Hah! Eat boot, and die!
What is your Live and Let Live limit?
