Becoming a señorita is marked by the onset of menstruation. When girls start to menstruate, the chaperoning by male kin can become even stricter than before (LeVine, 1993, p. 77). Many girls are not informed about the biological background of menstruation and they may think that they are going to die (LeVine, 1993, p. 77). Often, virginity is viewed as the most important trait for an unmarried girl, and fathers, mothers, and brothers alike guard the honor of a girl (LeVine, 1993; Melhuus, 1996). Nevertheless, there are significant variations. Because of economic necessity, it is not uncommon for young girls to have to work. In these cases, complete chaperoning is impossible. Also, given the increased level of education at present and thus longer time in school, more and more girls interact with boys within the school setting and without the observation of their families (LeVine, 1993, p. 78).
