Next door neighbour did some garden maintenance the other week and has left a pile of decaying twigs/leaves etc loose on the drive. There's no wall or fence between our driveways so I see it every time I leave the house and it's annoying the hell out of me, his bin was even stood next to the rubbish last week! I don't feel I want to knock the door and ask him to bin it, but I'm tempted to nip round when he is out and just clear it up?
