The postman knew the house was empty because he had never delivered any letters there. So, it was a shock on Monday morning when he saw a letter with that address.
Frowning, he went up to the house and saw a metal box with mail written on the lid. He posted the letter through then looked around. There was no signs of anybody.
Weeks and months passed, the postman kept delivering letters but he never saw anybody. Perhaps, no one had moved in and someone was just using the address? Criminals? Lovers?
Whoever it was, was none of his business and he was just doing a job.
