Making New Friends

I don't know if I developed a hatred for making new friends. Yes I was out walking early this morning at 3:30 AM. I was listening to music on my headphones so I won’t be bothered. I can see out the corner of my left eye a person walking behind me. My music stopped cause of the song ended. It sounded like he was talking on his speaker phone. I was about to finish my last lap around the block. I heard him so I stopped & turned around. He asked me where I live I told him in the apartments I just walked by. He asked if he could hangout with me. I politely said that's okay since I was still walking. I don't feel right hanging around with a complete stranger. I don't know if this has anything to do with it. He was a black male who seemed nice but my past experiences beg to differ. I tried to be nice once before what where did it get me nowhere. Again I was traveling to Parkland Hospital to pickup my prescriptions at about 3 AM. A Hispanic male asked if I have a spare cigarette he could have. I told him I don't smoke we laughed about it for a fee seconds. He walked off to ask someone else I guess. He looked back at me an walked back towards me really fast. He thought I was making a motion with my elbow. He punched & kicked me to the ground. He walked off so I was able to stand up on my own. I got a cut on my forehead so I decided to go get it looked at. He followed me & asked me if I was going to tell the police on him. I said no he didn't believe me so he asked for my backpack. Before I could give it to him he pulled it by the strap. I swung around & fell on the ground with such force. I couldn’t move my right leg I laid there. A couple of police officers asked me if I was okay. I said my right leg was immobile. They called for an ambulance to take me to the emergency room. I got luck cause I have financial assistance through Parkland. They did xrays found I broke my right femur. They got me into emergency surgery to fix me up. So you see I don't know if being nice gets me anywhere. It certainly doesn't seem to since I can't seem to stay out of trouble.
