In fact, I wonder if that very thing - the "exhaustingness" of pride - is one of the humbler reasons why humility has been so popular down through the ages. (And also - given how much we celebrate the Strenuous Life in these times - why it's so hugely unpopular today?)
(And, no, I didn't say any of those things to her.)
