I am Dorit Jaeger. I am from Saxony, in Germany, but I live in Vienna, Va. Am I an adult after 18 years of growing up? Am I an educated person after 12 years of school? Am I a woman after seven years of menstruation? Am I a vegetarian after 5 years of eating no meat? Am I a heterosexual after some boyfriends? Am I a good au pair after six weeks of caring for children? At what age does one know the answers to these things? Someone please tell me.
