Input: Article: I hate nosy   neighbors and it's very unlucky that I had one for myself. They moved in a couple of months back and although I never felt that they were a strange family, I've always hated the way they get "too close" to me, my house, my garden, and even my garbage cans. One day, my neighbors were mowing their lawn  . My garbage cans were near their lawn. For some strange reason, I found the wife looking through my garbage cans. I felt angry but since they were from a different culture, I thought that maybe it was "normal" from their ideas. That afternoon, the couple knocked on my front door. When I opened, they gave me a plastic bag. Inside were my old daily bills, credit cards and bank statements, and an old birthday card that my old uncle sent. They said that they were returning them to me because these documents contained very private information that may be used by others. I've heard it before. I asked them how those documents can be used by others and they started telling me their very own experience, which forced them to leave their home and move next door to us. The wife told me that she never destroyed the bills. They also had a "nosy neighbor" who looked through their garbage cans which they actually thought was pretty strange. Little did they know that this "nosy neighbor" was collecting their personal information from their rubbish. Then all their money was taken out from the bank by their neighbor. It was a very painful experience for all of them and they wanted to leave them all behind so they left. I was very thankful. They were not nosy neighbors. They simply didn't want us to experience the same thing that they did.
