Yes, if you are an experienced pilot you will get bored as an SO. It is part of the compromise of CX.
Every couple of months you should spend the money and go and fly a real aeroplane for an hour. It reminds you that you can still do that Pilot Sh**, which is very good for your self esteem.
If you arrive single to HKG as an SO it is like being put out to stud for three years. If you arrive with a partner it is the best chance you will ever have of travelling with them in a fascinating part of the world that will leave you both with wonderful lifetime memories. Those that spend all their time off going back to their home country are missing the point of coming to HKG in the first place.
Most SOs I talk to are itching to get back in the right seat, but they know that their present time off is a rare gift in the business world, and make the most of it.
Oh, and Caligula looks to have had a nose job, by an enemy. Or did the sculptor dare to add his syphilitic nose? He is I believe the Patron Saint of failed MBAs.
