Bleeding Rust

Every window key is rusty.
Window panes all need a clean.
I can't write more for fear that 'dusty'
rhymes its way into the scene!

You see my problem! Chose this rusty item for the Derelict Sunday challenge. Not sure if something as small as a window key can be counted as derelict, but it's not in its pristine youth! (Thanks to Marlieske for hosting the challenge.)

Mr PP is back home, safe and sound. Which is nice.
