But Dad I am a bit ashamed 2 arrive at my own college with my pure-gold Ferrari 599GTB, when my all teacher and many fellow student travel by train. Your son, Ahmed. Sheikh replies: My dear loving son. 20 million US Dollar has been transferred 2 ur account. Please stop embarrassing us. Go and get yourself a train too. Love, your Dad.
