what is human being?

baby girl from china
she was only 3 years old
she met a cruel driver
she was dead incident

when the baby girl hit by a car on a road
only 3 years old
a life just knew how to walk
a small body
a small step
a small voice
how did you her so cruel

even you don't know her
even you don't know what to do
even you can't do anything once it was happened

please.. take out your brain and heart!
Brain, to think how to solve the problem
Heart, to feel how pain was the girl and do something
not only see and act nothing.

so bad, the passerby did not lend their hand to help
so sad, a good person did not appear on the time
so mad, what is human being on this society!
