Office chairs in my house

Today I had a relatively strange story happen to me. It was a pretty regular day till I got home. When I got home there was a courier waiting for me with a huge delivery lying on the ground. I was pretty baffled with the situation and asked him what was that he wanted from me. He told me that he had a delivery addressed to me. I was pretty confused because I did not order anything in the past two months. He told me that the package that was lying on the ground consisted of two Office chairs of high quality. I had to tell him to take those Office chairs with him and send them back to the person that have sent them to me. He then got confused as well because he was a freshman, meaning he worked as a deliveryman for only one month, and never had a situation like this happen to him. However, I kept on saying that I did not need those Office chairs. My heart was broken, though, as he was even more confused than I was. I took the package and opened it and to my eyes appeared two really nice Office chairs. Believe me or not but I bought those chairs from him. I mean, the delivery was not paid yet and therefore, I had to pay for it. I wonder what the person who originally was to get the delivery will think.
