Who is this girl????

People look at you and judge you but what are they judging??? Cos what people see What you let them believe Could be so far from the truth I knew a girl once... she was popular with her friends and smiled all the time but deep down she felt trapped and not happy at all family problems,school,guys all this got to her and it wasnt till late at night when she cried herself to sleep... People look at you and judge you but what are they judging??? Cos what people see What you let them believe Could be so far from the truth I knew this other girl once... she was a good laugh, but the simpliest bad thing would trigger her off. A guy taunting her about her image, she would hit out and storm off crying, leaving her friends to chase after her and wonder what was wrong... People look at you and judge you but what are they judging??? Cos what people see What you let them believe Could be so far from the truth I know a girl... she is optimistic and dismisses other peoples negativity, shes a laugh and is good at giving advice...her friends adore her no end. But she hides behind a protective wall only becoming herself when she knows she is safe. You wonder who these girls are...these girls are all me.
