After his computer was on the fritz, 91-year-old Charles Krohn, an English professor at the University of St. Thomas, went to his daughter Julia's house to teach his students remotely. Enamored by his teaching style, Julia snapped a picture and shared it on Facebook.

Professor Krohn read each and every message with tears in his eyes.
