When you're hurt,you learn to hate.
On the other hand when you hurt someone, you're resented.
And of course depending on how human you are,you start to feel guilty as well.
However understanding such pain enables you to connect with others.
Knowing pain helps us to grow up,
And to grow up means to be able to think and to make decisions on your own.
To know and reflect on pain, and come up with your own answer.
To prevent the cycle of hatred and pain.
