The most important thing is to stay patient, when you deal with your parents. Ask them politely, if you wish to get your request accepted. In case you misbehave, your parents will get angry, which will eventually go against you.
Inform parents about your whereabouts
No matter where you go, you should inform your parents about the location. This way, they will trust you and believe that you are not up to something bad. Even if you are going to stay at a friend’s place, your parents should be aware of that.
Ensure them that you will stay in touch
With the availability of modern technology, you can ensure your parents that you will stay in touch with them constantly. This way, they will know that you are safe and will not worry about you.
Introduce your friends to your parents
Invite your friends at home and introduce them to your parents. Ask your friends to behave well in front of the elders, so that they allow you to stay together.
Request your siblings to convince your parents
If you are unable to convince your parents, get help from your siblings. They might be able to get permission for you.
Ask your friends to make a request
Another way of persuading your parents is by getting your fiends involved in the situation. When you are alone, you might be unable to accomplish your task, but this can be possible with the help of your friends.
Get help from your grandparents
If you have grandparents, you are so lucky because they can come in handy in such a situation. They will definitely support you and your parents will have no objections whatsoever.
