I had a knock on the door a couple of hours ago to ask if I wanted my block paved driveway cleaned as my neighbours are having it done. I said no. Last time neighbours had this done, all the rubbish went down the drain on my driveway and very soon after that the drain was blocked. I am at the end of one run and my neighbour is at the beginning of the next, so our drains are not linked. I have just looked at neighbour's driveway - they have no drains at all. I have two. WIBU to say something to the effect of "You will be careful, won't you, not to swish all the rubbish down my drain?"?
