Arab student to his dad

Dear Dad
Berlin is wonderful, the people are so nice and I really like it here, but Dad, I am a bit ashamed to arrive at my college with my 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 Dollars has just been transferred to your account. Please stop embarrassing us.

Go and get yourself a train too.
Love, your Dad.
