My sisters walked in on us...all three of them. And my mother. And my father that one time, and Findekáno - how many times? And your mother. And Aredhel, remember that time she made you help her with her tutoring work for a month so she wouldn't tell your father about that time in his study while he was away to Alqualondë?
