A Sheikh’s son goes to London for his Masters.A month later, he sends a letter to his parents saying:
”London is wonderful, people are nice and I really like it here, but I’m a bit ashamed to arrive to school with my gold BMW when all my professors travel by train.”
Sometime later he gets a letter from his dad with a 25 million pounds cheque saying:"Stop embarrassing us, go and get yourself a train too"
