Freedom is a person's civil or personal liberty. There is no country in the world where people are free to do whatever they like , as most countries are governed by laws. For teenagers, freedom means rebelling against their parents and doing whatever their peer group is doing at the time.

I presume you must have overweighed the meaning of freedom. Freedom is living up to some disciplines. You can pursuit your freedom as long as you don't undermine or bereave others'. Disciplines forbid you to do so. So be a lawful civilian before you behavior your freedom.
