Ex-Hedge Fund Analyst Finds Calling On YouTube -- "My cousin Nadia was having trouble placing into the pre-algebra class," Khan tells NPR's Robert Siegel. "So I talked to Nadia a little bit, and I said, 'How about you and me do some remote tutoring after I come home from work and you come home from school? We'll get a conference call going, and maybe we'll use instant messenger or we'll find something else.' "

Аналогичный случай произошел с Льюисом Керролом; тогда еще можно было фотографировать.
