Dog on a hot tin...

Roof ?

Popped to the post office mid afternoon and saw this. As I was taking the shot I heard:
Oi!
I turned round to see 3 hooded yoofs
Why are you takin' a photo of that?
I've never seen a dog on a roof before.
That's the garden, its always there.
OK shall I take a shot of you three instead?
Nah, they said and sidled off.
