Squirrels

[Norse]

Opening the window. Shouting. Rapping on the window. These we would do (although we recognize that it's like spitting into the wind).
But never kill.

I make a fool of myself shouting, rapping on the windows ... and, it used to work. Now, the crows and squirrels just look at me with an amused look and keep eating. I have to physically run out there and chase them off, but I would never kill them, unless I wanted squirrel stew.
