An Arab student

An Arab student sends an e-mail to hisdad, saying:
Dear Dad,
Berlin is wonderful, people are nice and I
really like it here, but Dad, I am a bit
ashamed to arrive at my college with my
pure-gold, Ferrari 599GTB. when all my
teachers and many fellow students
travel by train.
Your son, Nasser

The next day, Nasser gets a reply to his e-mail from his dad:
My dear loving son,
Ninety million US Dollars have just been
transferred to your account.
Please, stop embarrassing us. Go and
get yourself a train too.

Love, Your Dad
