The strange man

I might have been 16 when I decided to go out and sell candy off the streets. It was just something I just thought of doing until I was old enough to get a job. The sales were not so bad, it was okay for what I was doing. I also got into the habit of selling hazel nuts too. I was staying at farm for a while and realized that he was growing hazel nut trees, so I asked if I could try to sell some and he was more than willing to. The sales for hazel nuts were either equal or better than the sales of candy. I got a huge sale with a family that was going to use the hazel nuts for Christmas which I was glad to sell to them. I would sell the hazel nuts in small boxes that had magnets on the side to hold close and a golden bow on the top left side to look pleasing to the eye. Even though the sales were going alright every now and then. There was some times to where I had bad encounters with people. There was a couple I asked if they wanted to buy anything, then the conversation turned into them wondering if I was selling this stuff for crack and me having to explain to them I wasn't. The other was when I went up to an apartment complex and knocked on the upstairs door and was greeted by a guy in shorts and was more ripped more than me. I gave my usual speech which was "Hello, I'm going door to door selling candy and I was wondering if you wanted to buy some." He said no with a chuckle while smiling the whole time. He asked me if I just accept donations and I told him yes. He went inside of his apartment for a while and during that time, I couldn't help but thinking I was hearing someone moaning in pain. I couldn't really tell because of a landscaper using a chainsaw on some tree branches right outside the apartment. It was as if though the person was moaning in agony. After a while it stopped and the man came out with the money in hand and I told him thanks nervously then left. I didn't want to believe he had someone in his apartment that he was tourturing for his own amusement and was covering it up by seeming like he was a nice guy, but I didn't want to call the police and be wrong and make everybody think I'm crazy. As I made my way down the stairs, I was ready to call it a day and head home, but what stopped me was his sliding glass door. It seemed it was made to keep noise from the inside from going out. I hope that it's all in my mind and that I'm just imaging things, but one thing for sure. If he had asked me to wait inside, it wouldn't matter how much money he was going to give me. There was no way I was going to wait in that place for anything.
