A 30 year old man married a 25 year old woman. She died at age 50 and her husband was so devastated that he cried for years. Ten years after he stopped crying, he died. If he had lived to be 80, how many years was he a widower? I have seven letters. The first two stand for a boy. The first three stand for a girl. The first four stand for a brave boy. But all of my letters stand for a brave girl. What word am I?
