Such a short time left

My kids, like all kids, are growing rapidly and aging quickly (funny, I stopped all of this when I hit 29).  I can't help but think about how much time I have left with them.  My oldest is 15.  He is about to get his driver's permit and he will be a sophomore in high school this coming school year.  I have 3 years left with him until he graduates and goes to either college or the military (these are the choices he is juggling right now).  His freshman year was over in the blink of an eye and so I know that these next few years of high school for him will go by just as fast.  I have such a short time left with him. 
It is hard to make him understand this.  For him, the most important thing right now is his friends and social life.  I take a backseat to all of that.  And, as I have said before, I somewhat understand.  I think this is a normal phase for kids to go through.  Not an easy one for parents to go through though.  And, I do remind him all the time that his family will always be here for him while these friendships he has right now will most likely fade after graduation.  I understand the phase, I do not agree with it nor do I endorse it. 
My parents asked us several weeks ago to go on a camping trip with them that we will leave for this next week.  It would be my folks, my kids and myself.  The plan is to go camping in the mountains I grew up camping at that hold such wonderful memories for me.  I want my kids to look back and have those memories, too.  They are an important part of growing up and I have seriously prayed that God will give us this time to connect better.  I have always heard that if there is any opposition in a plan that can have positive results then that means the devil is fully aware of this and is trying his hardest to keep this from happening.  This is what I believe is happening with this camping trip. 
Yesterday, after having a yard sale to make extra money for this trip, my oldest sends me a text stating that he doesn't want to go.  His reason is that he wants a week "to chill" before two a days start the next week for football, but I know the real reason.  He can't stand to be away from his friends and the socialization he loves so much.  Oh, and no cell phone service either.  EEEKKK!  LOL!  I am torn about that, too.  I won't lie.  I love my cell.  I love that I can text, check email and FB and Google something at a whim.  But, as much as I love it, I need for my family to have this time together with no distractions.  I understand that my son thinks he is going to die and he has already told/threatened me by saying "I won't have any fun," which really means he is going to pout the entire time and try and make everyone else miserable.  He is with this dad for the weekend so we haven't had the chance to sit down and discuss this (fight about it), but I am sure we will this evening.  What I need him to understand is we do have such a short time left.  I can't squander this time a way.  I need to grab a hold of this chance to bond with my child and pray that the devil stay away.  I hope and pray that we don't get up there and he pouts like a baby all week, because he can probably do it.  I don't want this entire trip to be a bust due to his selfish behavior.  I may just lose it if that happens and get mid evil on his ass (love Pulp Fiction).  I will show him that the saying "if momma ain't happy, ain't nobody happy," definitely has truth in it. 
So, be praying about this situation.  Pray that he will understand and that this time can be used for us to bond and it will not be a time of misery and woe.  Pray that the devil stays at bay and only positive things come from this. I will let you know what happens!!!
