Read the letter from Dr Paul. It looks like a fresh engineer writing a letter ( with a attitude) and attempting to throw random questions to make the presence felt!
Read the letter from Mr Hock Tan, which appears to be highly polished ,diplomatic,on the dot and pressing to close on this "email thread" by COB right now !
The exchange is better Chairman and CEO. Where is SM (CEO still ? ), who has done nothing for the past many years except polished dance and talk.
