Time needs to be on your side when it you want to make sure your parents let you go out with friends. Find out when your parents have a few minutes to sit down and talk with you about your plans. Be accommodating to their schedules, not your own time.   If your family is usually all together for dinner, that would be a good time to ask. Or if your family does relaxes together on Sunday afternoons, that could be an ideal time to talk.  Plan accordingly for big events. If you’re asking about a concert that’s weeks away, don’t wait until the last minute to ask. Parents appreciate preparation, especially when money and transportation will be involved. Last minute plans usually won’t fly with parents, but sometimes you may be able to get permission to go to a low-profile hangout at a friend’s house if you spring it on them. More than likely your parents will say no to you regardless of the situation if they’re stressed or tired. Wait until any storms blow over and then ask if you can go hang out with friends.  Definitely make sure that you’re not in trouble or grounded before you ask for permission. You’ll need to work your way out of being grounded before you can expect your parents to let you do anything extra. Cleaning your room is a great way to show that you are mature. Additionally, it shows you can be organized and helpful. A good time to ask would be when you've finished your homework and chores for the week. Or to sweeten the deal, do all of those things on top of cleaning up after dinner. Don't forget to drop hints every so often so they aren't so surprised when you tell them. Bugging them incessantly will deter them from wanting to say yes to you. Annoyed parents are less likely to be very giving and you’re more likely to get in trouble if you push them too far. Give them a few days to think about your questions. Whatever your plans are, it’s in your best interest to try and plan things around your family’s day to day life. Don’t ask to talk with your parents about serious plans when it’s a busy errand...
