I can totally see where you're coming from. Here's what you do. For karmic prepayment, donate that pineapple chunk to a patient in real need. Then, kill the neighbor. Take him out somewhere in the woods, or the swamps, and just have some fuckin' fun. Bring some toys, a razor or two, some knives, barbed wire, hurricane wire, some piano wire. Some xanax, to prolong the party. A couple epi pens, to keep him with you, until you've expressed your anger at his hitting the pole and fuckin' your shit up. Then, with the rope you brought, hang yourself for being an ungrateful cunt, and not having the balls to talk to the guy that brought your lady into this world, and would most likely help out if the tables had turned. Even if he bitched about it -- it's help. Seriously, dude, you didn't step to him, when you have a problem with him, instead you came to a forum and talked shit about him.
That sacrifice to karma was for torturing and killing the guy. You hanging yourself will balance the scales for your disrespect for your ancestors.
