In a faraway land, there was a place called Forgetland. It was a place where people could have their memories erased. Many people, burdened with sad memories, went there. Among them were two friends.
When they reached there, they were called one by one. One of the friends went first, and returned after a while. He looked happy.
His friend was happy to see him happy too, and went to greet him. He asked him how he felt. He replied, "I am feeling very happy, but who are you?"
