They will erase the whiteboard before class and carry half of my equipment back to the office after. One got up by 5 a.m. as an undergraduate so he could make it to his 1200 seat classroom in time to line up for a good seat. ...the only chance he had of reading the board. Not so here. One has had three scorpion stings, most have had malaria at least once. They are from 14 different countries, mostly sub-Saharan Africa and they get along. They even get along with me! They are a pleasure to teach!
