SO you tried to do the right thing and it blow up in your face what now?

This was my delima my sister an I were driving to a friends house and we saw a gurl that we had seen at her house before. So being the good hearted person I am I asked her if she was in need of a ride. She told me she was going to the same place as us so when we pulled up my sister got out the truck and went over to the other truck that had 6 people in it. She came back and said that they want her to go with them. Thats when the girl got out the truck and walked over and started cusing out the guy who owned the truck. It turned out that she was engaged to the guy and he was with her best friend in the back seat of his own truck with her. Well my sister being the big mouth that she has. Was talking shit about the guy the rest of the way to the house after the girl had asked if we had seen him. She was also talking about the girl that he was all over the last couple of weekends. Long story short I was taken into a room pinned against the wall by two guys that were with him. Wanting to know why I would set him up like I did. I told them the truth but they werent trying to hear it they were already drunk and high so its not like they knew what was going on really. Things got way out of control when one of the guys that were holding me's sister walked in and they turned their anger to her instead. Next thing I know one of the guys is waving around a gun. I was then let go and everyone was running I just stood there for a moment before grabbing onto the guy with the gun. He dropped to the floor and the gun went off. Everyone freaked out and dropped to the ground inside and outside. I tried to pick the guy up but he was to heavy. I turned him over and searched for holes or blood or anything. I couldnt find anything. I was so scared. I was freaking out myself. He opened his eyes and said im drunk "WOOOOO". I just laughed thats all I could do before he passed out again. The gun was facing the ground and the bullet went down into the dirt. I was very lucky that he didnt get hurt or even killed I took his gun and hid it from him. After that they all took off and everything seemed like it was back to normal again. I went to sleep and woke up every hour just incase though I just couldnt go to sleep thinking that they could come back after a few more drinks. I woke up with my friends brother sleeping on me. I guess he came in and just passed out on me or something. I got up and went to work. So far I have had three people call saying they dont remember much of last night and they want me to fill them in. Well that is the gist of it and yes the guys that pinned me said sorry and that they dont remember doing it.  SO DID I SCARE YOU?
