You wake up all of a sudden and catch a thief!
He has already filled up his bags with your stuff. 

Would you allow them to carry even a spoon with them? A pen? A small matchstick?
No, right?

Then how is it that someone enters the abode of our happiness, takes it away and we let them?
How is it that people make us unhappy, and we let them?
Why do we give people the permission to decide our happiness?

Our happiness, just like the possessions in our home, is earned by us, is to be protected by us and nurtured by us.

We are both the generators and the guardians of our happiness.
