Not many people here are gonna tell you this because it is a big secret... But your parents are idiots. They are going to get stupider and stupider for the next several years. By the time you are 15, you will be surprised they can tie their own shoes.
And you just KNOW that they were never kids themselves. Well, we know they were, but YOUR parents obviously can't remember what it is like to be a kid. And even though you are super cool, you must be some kind of genetic miracle because there is no way your parents were cool.
Plus they seem to have this ridiculous attitude that just because they go to work and provide for everything you have and do, that they somehow should have some input in what you can and cannot do.
Some parents even think they know what it is like to be a teen, but of course they don't. It has probably been 20 years or more since they were your age and they don't know what it is like now.
And they can't possibly love you and care about you and be trying to do what is best for you. I mean, sure - just a few years ago they were taking pictures of you and showing them off to anyone that would listen and wiping your butt every time you crapped yourself, but they don't care about you now, right? Cause if they did, they would let you do anything you wanted!
But then, something miraculous is going to happen. Sometime between 20-30 years old - depending on how intelligent YOU actually are - your parents are going to get smarter. It is almost like they started taking smart pills or something. Suddenly, you start to wonder that maybe, just maybe, they weren't as dumb as you thought when you were a self-centered teen who thought the world revolved around what you wanted to do.
And then, if you make it to this point, you will have your first child. It will be like a switch flips in your brain. You will fall instantly in love with this screaming, crying, peeing and pooping little ingrate that doesn't care about anything but itself.
And miracle of miracles, in a year or so, that little beast will begin to smile at you and soon will worship the ground you walk on. You will be the coolest, most amazing parent in the universe, along with your wife.
Enjoy it, you might get 5-10 years of that if you are lucky.
Then one day your punk-ass 13 year-old is going to want a plasma ray gun that can eliminate all life on earth as we know it (Using Moore's law here) and time will stand still as your travel through a memory tunnel back to this day many years ago when you thought your parents were fools because they wouldn't let you burn your friends eyes out with a laser.
If you have half a soul, you will realize how awesome your parents were, not to have just taken you out back, hit you in the head with a shovel and buried you in the woods and moved to another state.
That's just my take on it.
The short version is that it isn't a real good idea to put lasers on things you are going to point at friends. Your parents are right, you aren't ready for it yet.
Good luck!
