An arab's royal son goes to Germany to study.
A month later,,,
He wrote to his dad saying:
Berlin is wonderful,
people are nice and I really like it here,
but I'm a bit ashamed to arrive to school
with gold Mercedes when all my teacher's travel by train.
::
A few day's later he got a letter from his dad
with a twenty million dollar cheque saying:
"Stop embarrassing us,
Go get yourself a train too"
