How? With a chain saw and a set of loppers. Cut a huge limb/trunk off one of my scheffleras and damn near destroyed two of my white birds of paradise because the foliage was over "his" side of the fence.
Let me give ya a little background. My yard looks nice. I'm incredibly anal (hear that Charmin?) about it keeping it that way and I probably spend way too much time and effort on it as it is, but I digress. His house is two story and is set back a little further than my one story house. I'm just a poor white boy. So, if it were not for these plants and the heights they grow to, he could stand on his back porch and have free sight to my pool. What happens in my pool, stays in my pool. Know what I mean? It's a pure privacy issue. I trim them, and I'm very systematic about how I trim them. Now his yard looks like feces. He has resodded twice in the 10 years that we have lived there. It still looks like feces. To him, the reason it looks like feces is because of my oak trees and these scheffleras and birds. He can't get it through his thick skull that we have no problems with grass growing under the oaks in our yard, but he does in his. He can't get it through his thick skull that his two story home is blocking the sun in that part of his yard and not my scheffleras and birds. He can't get it through his thick skull that watering your lawn twice a day instead of two-three times a week will kill the hell out of your grass and do nothing but foster the environment for weeds. So, when we were gone on vacation, he took it into his own hands. Jackazz. So when we got back, I immediately noticed it and stormed over to ask him if he had seen anybody in my back yard destroying my plants while we were gone and that led to a rather unpleasant conversation in which I ended it by telling him to go fornicate himself. All he had to do was apologize, I gave him plenty of opportunities and he refused. It sucked, man. I didn't enjoy it, the whole neighborhood didn't enjoy it, and when my wife happened upon his wife by chance at the doctor's office and she broke down crying saying she missed us, blah, blah, blah, I decided I would be the bigger man and, own my terms, reconcile. So we went over one night when they had people over and after he apologized I shook his hand and we've been working on it.
What a wonderful fairy tale. Sorry for the threadjack.
