My bird problem.
During the winter I keep my car in storage. It sits in a closed garage/barn, together with my tools and spare Fencing equipment.
So the garage is locked, except for the brief moments when I need some tools, or my fencing equipment. Somehow a bird keeps managing to get inside, sit on a support beam, shit on my car, and then leave, without anyone ever noticing.
My car solely gets shit on, when it's inside the garage. I have never seen this bird, I've never heard this bird, I solely keep finding the smudges it leaves behind. Solely on that fender. And it's put me in this never ending loop of cleaning up smudges only to have them reappear the following week.
It's driving me insane.
