Dear Father,
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 father:
My dear loving son,
Twenty million dollars from American and Canadian gas pumps has just been transferred to your account. Please stop embarrassing us both. Go immediately and get yourself a train too.
Allahu Ackbar, your Father
