Anyway I've copied the card I've sent him below:
The note I included with the card:
When the markets slip don't lose your balance. There are people counting on you to make them money which in turn makes you money which in turn makes the Gates foundation wealthier which allows them to screw up the emerging world with their handouts.
Lastly, I like to quote Winny Churchill when I am feeling particularly giddy,
"Although prepared for martyrdom, I preferred that it be postponed." - Winston Churchill
