Waiting

Water, water, water; why can't it just rain for once here, just like how it does at all those other places the other guys told me about. These were the words going through young David's mind as he left the ruins of the old mansion at dusk in search of water for the next two days. There were three places David knew of, where water can often be found. The one David was heading to was the closest of the 3,a good 20 minutes walk from the ruins. 
All that David was wearing was a torn, shabby full Tee, and some worn baggy pants; this was what he has been wearing ever since his been here.David had to be careful,  the desert never stops changing, and getting lost out here means only one thing. David and all the others have to travel under the moonlight as you wouldn't last an hour out during the day. 
David arrived at the place. It was a small, spring fed water hole no more than a metre in diameter. It was located at the bottom of two towering dunes of sand and was surrounded by small shrubs and a lonely palm tree. When David got to the hole there was only about a bucket or so worth of water but it would be enough as all David had to transport the water was an old, rust covered watering can which somehow made its way to the mansions ruins. After filling the can and having a quick drink, David was soon heading back to the place he had left 20 minutes before. As David approached the ruins old, rotting, pine wood door he noticed 2 of the other 10 or so boys he shared with coming back as well. Both seemed to be sharing the load of some sort of animals' carcass. If this was the case, all of the gang will be having full stomachs for the next week or so.
 When David walked in he was greeted by yet another one of the roofs panels almost squashing him as flat as a stone and some commentary by one of David's best housemates, Sam, the second oldest of the 10 boy's at 16 years of age who is only topped by John at 21 or so he says. The way things work around here is the older you are, the more power you posses. This puts young David, who's 9, right at the bottom of the pecking order only having more power then Vincent who thinks his 10 but is more like 6. 
"Sam, can you refresh my mind on how we got here and why we are still here?"Politely asked David.
"Well, we we got here via our stupid pilot trying to fly a fully loaded 747 through some volcanoes ash cloud, then crashing somewhere over there and us guys are the only ones that got out before it exploded."said Sam.
"And why are we still here?"Asked David.
"we're still here because we're still waiting for those people that are meant to rescue us." Answered Sam.
"And why don't we just find some other way of  getting out of here?" Asked David once more.
"Because it's not like a radar dude could miss a 747 crashing, or could he?." Questioned Sam.
"I don't know, but That doesn't matter right now cause look what we have here." Said David.
"Shots the rump!" yelled out Chris.
