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
