E-mail from Arab student to his dad

 
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
