An Arab student 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 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，
Twenty million US Dollar has just been transferred
to your account. Please stop embarrassing us.
Go and get yourself a train too.
Love, your Dad 愛你的老爸
