An Arab student studying in Europe phones his dad
Dad: "How's your life going, son?"
Son: "It's going well, Dad."
Dad: "Is something wrong? You don't sound too happy?"
Son: "No Dad, everything's fine. Berlin is wonderful, people are nice and I really like it here."
Dad: "Son, tell me the truth. I know something's not right."
Son: "Dad, I am a bit ashamed to drive to my college with my pure-gold Ferrari 599 GTB, when all my teachers and many fellow students travel by train."
Dad: "My dear son, why didn't you say so earlier? I will send you 18 million Euros this instant!
Please stop embarrassing us, and go and buy yourself a train too!"
