All my life, I remember whenever we went out to a show or play or even to the shops, we would be looking at the people around us. Or even the people in the show, begging, pleading with them with our eyes to please please notice us. Please see us in the crowd. Please somehow see us and know that we are special and save us from the life we live. Please please notice us and know that something is wrong and do something to help us. We still do it today as adults and still no one ever does.
When they don't notice as they never do, we leave feeling we are invisible and not important, and that 'they' are right and we have no value. Otherwise someone would have noticed the girl/woman in the 5 row dying inside.
But i guess we can't be seem.
