you really don't want to feud with a neighbour. that makes life very awkward. I chopped down some of my neighbour's shrubs (not the chicago family) and part of a big tree because she saw me doing my side and asked me to do the same for her because she couldn't control the growth. Then she accused me of killing off her plants! I was doing her a favour at her request! That was last year and then last week she tells me how wonderful the flowers are this year and the pruning i did last year really helped. Not a word of apology about accusing me of killing her plants.
