Sheikh's Son (Nasser) goes to Germany to study. A month later, Nasser sends an e-mail to his Dad saying:
Berlin is wonderful, people are nice and I really like it here, but Dad, I am bit ashamed to arrive to my college with my Gold Mercedes , when all my Teachers travel by train.
Your Son, Nasser
Sometime later Nasser gets reply to his e-mail from his Dad:
Please stop embarrassing us, Forty Million Dollars transferred to your account, go and get a train for yourself too.
Tons of love, Your Dad
