The gent in Seat 20B on the London City BA flight was lost in his own MacBook world. He was merrily typing a letter to Colin Buchan, the chairman of the investment committee of Standard Life Investments, who is about to retire.
It was a flowery and personal epistle. Lovely stuff indeed. And yes, you're right, it is down-right rude to read other people's mail. Discretion prevents Agenda from revealing any more, suffice to say that, had this been someone more junior revealing details of Standard Life Investments' portfolio, then there would be stiff questions being asked at No 1 George Street.
Thankfully, it was only Rod Paris, the chief investment officer of Standard Life Investment. Why do such clever people think sitting on an aeroplane means you're surrounded by an invisible bubble?
