Been there, done that. We pay for trash quarterly around here. They pick up on Wednesdays. I don't put my trash out till early Wed morning. Awhile back, I walked out to put another bag out, and found 2 white bags (we also use black), with our trash. I opened one and saw the name and address of a new guy across the street. I picked up the bags, and put them on his porch, figuring he would get the message. The next week, the same thing happened, only this time there are 3 bags, and 2 boxes of crap. I again put his stuff back on his porch. The third week it happened and I was ticked off. I printed out a letter, telling him that around here we pay for our trash pick up, and you aren't allowed to 'share' with neighbors. I left him the name and # of the trash co. and told him if I found his trash over here again, I would be taking it up with his landlord. I put all his trash right outside his back door, so he had to trip over it if he wanted to get by it, lol.
Forward to this past summer. I was out doing yard work, and this guy walks over and hands me a bucket filled with black walnuts. He said why are your walnuts across the street in our driveway. I said what do you expect me to do..direct where they fall and roll to?, I couldn't believe he was asking me such a stupid thing. He says well you did it with my trash. I said your trash was your trash, we pay for pick up. You can't help where leaves or walnuts fall off a tree. We are on the high side of the street, so of course they are going to roll across the street since it's pitched down? He walks away and says well don't let it happen again??? Some people are just plain looney!
