When I was robbed

A gun was pointing at my head just thinking what should I do. In the summer I worked at my dad store. It was a mini market. Every Friday my dad and my mom goes to the moesque at 12:00 and comes back at 3:00 or sometimes come back at 5:00, thats if they go by stuff for the Store. My cousin and I were in the Store we were talking and we were going outside and talking to some girls. So we came back in the store and a man comes in and he looks familiar because he comes in often, and my brother in law comes in to and I asked the man what do he need he says change for a 100.00 bill and I said no but we did had it. He lefted because my brother in law was there so my brother in law and I was talking so I walked him to his car and I came back in. My cousin had bought some chinese food and we were eating and the man comes back in and says that I am going to rob you and I was like no your not and then I went into the cashier part and locked the door. So he took out the gun and pointed it at me but I was thinking the money or my life so I chose the money I gave him all the money and he ran off we called the cops and when the cops came They were asking me questions but I was so petrified to talk so my cousins and my aounts talked for me. My dad and mom came and saw cops around here so they asked what happened they explain it to them and my dad was ready to fight. But my mom calmed him down. So they couldnt find him but I was like its cool so two days later I see him and he acted liked nothing happened. So I just lefted it alone. Oneday I see him getting arrested for robbery and a possession of a gun and that day I was happy didnt know what to say but thats what he get.
