A text that I'd written in English

the next text is a text that I had to wrote in my academy for an exam:

      "It was only a small mistake but it changed my live for ever. I went to a circus alone because I thought that that circus was well for pass a good time. When I entered there and I saw that I was the only one , I thought: "Maybe the circus starts later". So I went outside again to ask someone what time the circus started. I didn't see anyone, so I entered again and I stayed there waiting. Later some people also entered, but they were from the circus. They came closer to me and suddenly, they started hitting me. Then, I got asleep and when I woke up I didn't know where I was. I was wit those men that had hit me before. I asked them what was happening and they told me that if I didn't want to have problems I had to be in silence. Every time I said something, they hit me or they pointed at me with a pistol. 
      I was with them for many weeks, and I lived in very bad conditions. And finally they let me go. But I didn't know where I was, and since then I haven't been with my family. And all because I made the small mistake of going to that circus."
