[after mentioning some of his ancestors who were careless with money
The only way to keep an estate like this together is not to take your eye off the ball, to be careful, not to gamble. That's why we've held our land and our house for 800 years. Not, that is, that we haven't had the odd complete cretin, but luckily we haven't two in a row. I mean, the old rule of thumb is a family and an estate can survive one idiot, but can't survive two.
