Re: I am telling the truth
Okay so let me get this straight -- your parents don't want you going to clubs, because you're rather young, and you lied to them and told them it was all-ages (Even though you have to be 16 to get in, which is not, technically, alla ges) and they still won't let you go.
Your defense is that if your parents don't let you go out partying now, presumably when you are WAY TOO YOUNG TO BE DOING SO, when you are going to college you might be out partying then, and Oh Lawd What Will They Do Then?
Okay, so for starters, what should you tell them?
THE TRUTH. Do not lie to your parents. Do not. I know that it seems to you like they're being hideously unreasonably strict omg etc., but by lying to them and setting a statement for "OH I am just going to a friends house" or whatever you are undermining your own safety.
When you are in college, presumably you will be mature enough and old enough to get into the clubs legally and to not be an idiot about letting people know where you're going and how long you'll be gone. Presumably your parents will recognize that you are now a collegiate adult and are thusly deserving of the respects usually afforded to a collegiate adult -- that is, unless you managed to screw it up when you were young by being perennially deceitful to them.
