NDN has very large conifer in their garden, very close to the border with us. There are many branches over hanging in our garden and also the roots have broken through our paving causing quite a mess and making it very uneven. Also birds sit in there all day covering the paving in bird muck, which is not ideal with a toddler playing around. Spoke to them about getting it under control but they don't seem receptive and say bird muck is natural! AIBU to insist that branches and roots are cut back? At our expense of course.
