A stranger is a person.
They're fighting something on the inside.
Just like you they do good things.
Just like you they make mistakes.

A stranger walking down the street.
They could save your life someday.
They could end your life someday.
You never know what could happen.

A stranger could be dying inside.
They could need someone to confide.
A slight hint of kindness could change their life.
If you do something nice you could be friends.

What if that stranger is someone who will change you?
What if that stranger is the one you need?
You may never know.
What if you ruin their day?

A random hello or shove could change your life.
Don't take them for granted.  
Strangers may control your life.
A stranger is a person too.
