We live on the 10th floor. In the basement of the building are a number of small rubbish skips which sit beneath a rubbish chute.
The rubbish chute starts in a small room along the corridor on our floor, through each of the other 9 floors and deposits our rubbish into the skip.
The door of the chute has a light, which is occasionally red. I have no idea what this means, but I avoid placing anything in the chute when it is on.
At other times I throw our rubbish, carefully sealed in small carrier bags, down the chute It is a small and childish pleasure, but I do enjoy listening to the bag as it bumps the sides of the chute down all 10 floors.
