Imagine the scene. You are tackling a big old bush in the back garden (no, this is not a euphemism) and you are discarding branches here, there and everywhere. You feel a little melancholy as they land, distressingly haphazardly. You feel you cannot merely scoop them up and condemn them to the recycling bin. So instead you let them see out the last of their days in a selection of makeshift vases, bringing a sense of Roman decadence to a bright and airy room.
