I had a biology teacher who lived during the depression and he told us the story of his child hood and then we had to take a test over his life in the depression. We failed...EPICALLY
My Drawing II teacher is known for doing this! He's 70, and loves to interact with the students with so many of his life stories. I always love it when he would go on rants about this experiences (nothing to do with drawing or art) and with his personality, they would be so funny!
That sucks..
It takes up most of the time..xDD
