This is Sam.
Sam wants you to understand the situation from the scorpion point of view. Nobody was living in the house, much less the air ducts! Can't we all just... get along?
I told Sam that his buddies are welcome to live outside in my woods but we were afraid we would reflexively kill them if they live in the house. Especially if they live in our similar-to-leaf-cover bedsheets. Totally involuntary response on our part, you understand. Safest for all if they vacate.
Except you, Sam. You can stay.
