Those ideas are all great...and funny..and vindictive as hell...but anyone can go by a camera and record you doing this shit. Then it's not funny anymore. The whole purpose of torturing someone is to, well, torture them, but not get caught in the process. What good does all the abuse do when he gets charged with something and then has to spend $$ on legal fees? If you want to piss him off and don't care about the aftermath, then go ahead and throw a brick through his windshield. There. Done. If you are going to leave piss and shit and vaseline all over the place for him to find, don't you think he will figure out real quick who did it? Then what? Now he retaliates...then you do..rinse repeat. If you are going to do something like that, you had better make sure you are long gone before you do it. if you plan on living there for a while, you need to resort to psychological warfare or do things that he will have absolutely NO idea you had anything to do with. This isn't 8 yr old next door neighbor games we are talking about. These are adults who have shit to lose and are able to buy guns and other weapons. All this retaliation talk is funny...and nice...but doesn't make a whole lotta sense if you live right next door to the person. Use your head. For those who haven't read The Art of War, go pick up a copy. Hell you can probably find it online somewhere free.
