"GUYS WE HAVE TO GET OUT OF HERE!!" "We'll be out soon.. " "I told you that this is gonna blow we HAVE to go. NOW!" "Okay. Just go look in the closet and make sure everything is out before we go." "Okay. Whatever." *Walks in closet and looks around* *Door slams * "Guys" "No. We are so tired of you acting like your the boss of everyone. So, just to make sure that you won't boss us or anyone else around anymore. You won't be coming out this closet. EVER. " "Guys please I have a wife and kids don't do this. ", "I'm sorry. Well not really but it sounded good for a second."  "Guys open the door" *Pounding on door* "Guys?? "2 days Later. *Knock on door* "David open the door I'm on the phone." " Okay!'' "Ma it's the police" "What?!"Then his mom walks up to the door and looks at the cop. He tells her that he found her husband dead on the beach. He explains the police department believes that he got caught in a fire, then he says they are doing everything they can to find out exactly what happened. She thanks him and he leaves, so they are alone. His mom leaves and goes upstairs crying all the way up both floors. Later that day when both of them get themselves together they finally talk.  Later that day he calls his friend and talks to him because he doesn't want to talk to his mom about how he is feeling. His friend comes over and stays with him for a while until he felt better. He was staying over a lot, so his mom brought them some things to have and wear while he was staying there. He stayed there for about 1 year to help them and keep them stable. 3 years later. Vaughn came over to David's house and they talked. David told Vaughn about his plan and what he wanted to do. He said"Okay. So, it's been almost 4 years since my dad died. I think it's time I find who did this to him. What do you think??"  Then Vaughn said"I think your crazy! Don't you remember when the officer clearly stated that he died in a fire dude?" David thinks for a minute then responds"I think my dad is smarter than that and he knows when a fire is coming. If anyone knows my dad it's me and I know that he would never stay somewhere that would even have a slight chance of catching on fire! I want to find out who did this and put him through what he put me, you, and my family through." Vaughn thought about it for a minute and said"He did put us through a lot. It even killed me and he isn't even my dad! But think about it.. What if it was that he died in a fire because he was maybe in the wrong place at the wrong time? If we kill someone then we will be on the run forever. Especially if he atually did die in a fire man. We would never be able to see any of our family again. We would have to cut our hair and change our names and all that stuff dude. Do you really want to do that? What would your dad say if he even knew you were thinking about doing this?" David knew he was going to say this to him so he smiled and said "He would say I'm right and that you can't trust anyone. Not even the cops. So you in?" Vaughn laughed"I'm in! Now lets go find who killed our dad." David and Vaughn hugged and went downstairs to tell David's mom they would see her later. So David and Vaughn got in their cars and got ready to go. They are best friends, they didn't even have to ask they knew exactly where to go. That is where they always go when they have to think about something very serious. They went to the mall and went to the food court and went to Chipotle.  After they ate they talked about what to do about finding the guy who killed their dad. They came up with a plan they knew would be bulletproof. They would do some research for a few days and find the people who were there and find out who was with their dad when he died. They both looked into the fire and knew that  3 people made it out before the fire and all 3 of those guys hated his dad. So all they had to do was look into those guys and find out what they were doing and find out which one killed his dad.  They already knew where one of the guys who made it out was, because their dad had once took them with him to go pick something up from the guy and take them out for food. So they looked the guy up and found out his name was Joey. So they went to his house and knocked on the door. They found out he was in the building his dad was in just like they thought. So David asked him"Did you see what happened to my dad? How did he die?" The guy was old and mean he responded after a second and said"I don't know how he died. He must've gotten caught in the fire. Either way I don't care, I never like him anyways. I'm actually happy he is dead." Then as soon as he said that something inside David and Vaughn clicked and they went crazy. So they beat the guy up really bad, after that they heard him laying on the floor.
