What if you managed to turn off the alarm and the house got broken into? They have alarms for your safety and for theirs and it would be a terrible idea to mess with them. You'd be putting your whole family at risk for a burglary or worse. Furthermore, you would totally lose their trust.
Why do you want to sneak out? If there is somewhere to go, can't you just ask them? You should be upfront and honest with your parents. Otherwise how can you make them understand you're mature enough to be trusted to go out at night?
I don't mean to be mean, I am just trying to explain why this is not the best solution.
Ahhh...."When I first read this question".......The music from the "Great Escape" came into my head. Imagine your son or daughter tunneling thru the basement to get out.
I'm trying to sneak out but my prnts hav alarms on evry entrance/exit in the house. (Windows included). My rooms in the basement. The only way to turn off the alarm is by going into my parents room and disarming it. Does anybody know how I can manage to work around the alarm without turning it off???? I can't think of anything but I'm not very crafty with this sorta thing....
