When you are so picky that you vacum your chicken coop and then fib to friends that you used the vacum to clear out the cobb webs because it is less dust for your allergies.
...when you sit on the coop floor way longer than you want to because your legs are covered with sleeping hens and the shy one wedges herself into the crook of your arm and finally falls asleep. How can you disturb them for a long time? It's a good feeling to interact with another species to the point of real trust.
