i was wondering if greg mortensen, if you knew anything about the work that he's doing and what you think about that. and also, perhaps, the east india tea company which, although it doesn't exist today, i think it's still around in some other form, if you could comment on that. >> well, we like -- greg mortensen has certainly brought a lot of attention to the suffering of the afghanistan and pakistani people. i think what i would say -- and i'm not just saying this as an author. i really wish everybody who has read three cups of tea would also read "invisible history" and "crossing zero" for the simple reason that what we're dealing with in our work is a way to try and understand how every school that is built in pakistan and afghanistan gets destroyed over and over and over and over and over and over again. so this is really where we, you know, we view mortensen's work. at some level i'd say i'm sure he'd like us, he'd like to be put out of business. he'd rather not have to keep rebuilding those schools. and i think that's what our work is about, is showing people how it actually happen
