This has reminded me of a guy that lives directly across from me.
One morning, on recycling collection day, I came home from the school run before the truck had been, and noticed an empty Lilt bottle had blown in to the road. Not my recycling, but I picked it up and popped it in my box, because littering.
An hour or so later I happened to look out the window and saw that the bottle had blown out of my box, and was in the road again. The guy who lives across from me picked it up, and rather than just pop it in his soon to be emptied recycling box that was centimetres away from him, walked across the road and put it in mine.
Obviously, not an issue for it to be in my recycling, but wtf? We don't get charged by item. His box was a lot emptier than mine. Just be a good citizen and pick it up!
Anyway, I'd rather live in a world full of people that don't mind something being put in to their soon to be emptied bin, than miserable people with too much time of their hands I guess.
