Expression

Driving home from school today was really depressing. The amount of mad (schizophrenic) people or homeless people that I pass on my way home, really got me today. I am not sure why it was today of all days that it affected me, but it did. Sometimes the things they say are funny, but their existence, their meagre existence, is not only pitiful, but heart-breaking. What can we do for these people? I want to live a life of purpose, one that will change people's lives. I don't want to be another observer I want to do something, to change something, to be something.....
