You can give me pain 
The sorrow does hurt 
As being hurt is hurtful 
You cannot imagine it even since you do not even have emotions 
If you had feelings then you would never be so cruel 
To me or to anybody else 
Only, if you had a heart, then you would realize 
Being me has never been simple 
Your cruelty you continue towards me 
If you had an heart then everything would be different 
This world would have been much nicer place for you and me 
Only if you had an heart.
