Difficult to figure out the meaning of liberty

She was in Chicago alongwith her parents.She had small argument with her parents, so she looks bit disappointed in snap, though cute. Actually she wanted to sit on top of the wall (where she is sitting right now) and her parents kept denying her offer. Ultimately she won and uplifted in her desired position. She would have been more happy, had her offer accected earlier. Looks like she is searching the meaning of freedom.
