I come from a long line of school teachers. My grandmother, Elsie Benson Storms, taught in a one-room country schoolhouse in Iowa. She continued teaching well into her late 30s, which delayed her marriage to my grandfather. In the early part of the 1900s teachers signed contracts that required them to abide by the following set of strict rules: You will not marry during the term of your contract. You are not to keep company with men. You must be home between the hours of 8 p.m. and 6 a.m. unless attending a school function. You may not loiter downtown in any ice cream stores. You may not travel beyond the city limits unless you have the permission of the chairman of the board. You may not smoke cigarettes. You may not under any circumstances dye your hair. You may not dress in bright colors. You may not ride in a carriage or automobile with any man unless he is your father or brother. You must wear at least two petticoats. Your dresses must not be any shorter...
