Down in the DC corridor [Gaithersburg/Rockville/Bethesda] the grass beside the all-glass buildings is littered with the bodies of birds, all the time.
No one cares.
Once in a while, you pass a building and see a poster or masking tape X, where the cubicle dweller has attempted to warn off the birds.
When I was young boy, I knew a couple of kids that had grown up their first years in Samoa (their dad was a medical missionary there).
Back then, they didn’t have sliding glass doors or glass windows in their fales, they were just open.
Anyway, when they first moved here one of these kids ended up running through a sliding glass door. He didn’t realize it was there because he’d never seen one before. Off to emergency he went with some pretty bad cuts.
