I don't know quite where to put this thread so have chosen 'other subjects.' My DH and I, both elderly, live in a ground floor flat with a small garden at the back. Directly above the garden is the bathroom window of the first floor flat, which houses one lady around thirty and her mother. We keep finding chopped up pieces of bread in our garden, directly underneath their bathroom window, so it is obvious that they are throwing the bread onto our garden. We don't have much contact with these people apart from to say hello if we happen to meet. We don't want to cause trouble, but have been thinking of popping a note in their letter box asking them to stop. What would you do? Would a note result in more hostility? (We do see this as hostile behaviour).
