Rich Arabs

Sheikh's Son (Nasser) goes to Germany to study. A month later, Nasser sends an e-mail to his Dad saying:

Dear Dad,

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:
Loving son,

Please stop embarrassing us, Forty Million Dollars transferred to your account, go and get a train for yourself too.

Tons of love, Your Dad
;)
