Viswasi and Aviswasi

One day a man called Viswas went to a barber shop to cut his hair. The
barber Aviswas  was a very friendly person and entertained his
customers by talking to them about  various topics while cutting their
hair. This time he started talking about God to Viswas. Aviswas said:
I do not believe in the existence of God.

Then Viswas asked the reason for his statement. Then Aviswas said:
Sir, you just look at the world. Nothing is fair. I see many people
get sick, so many people are poor, so many people are suffering. If
God existed, how can He allow these things happen? If He is all
powerful, can't He make a world with no distress or disease?

Viswas thought for a while and when Aviswas finished cutting his hair,
he paid him and came out of the barber shop. He started walking and he
saw a man with long hair and untrimmed beard. After a few more steps,
he saw another person with long beard and somewhat long unkempt hair.
He walked back to  Aviswas's barber shop and showed Aviswas these two
men and told him: "Aviswas, I do not believe in the existence of
barbers in this world. If there were barbers, there should not be
people walking around with dirty, long hair and untrimmed beard like
this".

Aviswas said: " How can you say that? I am a barber and just now I cut
your hair.I am cutting the hair of at least 15-20 people a day. Those
people you showed do not come to me. Then how can I cut it for them?
Do not make this silly conclusion.

Viswas said: How can you say God does not exist? God too exists. But
people have to go to Him. He will not come to them. Do not make this
silly conclusion.

Viswas left with out waiting for Aviswas's next statement. Next day
people noticed that the writing on the board outside the barber shop
had changed from Aviswasi Barber shop to Viswasi Barber shop!
