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
