Here's the history. Years ago our next-door neighbor built a fence around their yard -- all four sides. Then the people who owned our house at the time built a fence around their (our) yard, only fencing on three sides because they could hook onto the existing fence on the fourth side. Then we bought the house and moved in.
Now, all the fences need to be painted. Who is responsible for painting what fence? Do we all just paint the parts that we (or the people who lived here before) built? Or do we each paint the side of the fence between us that faces us?
The fences are similar in style and color but not identical.
