Nussbaum, Daedalus, 22 Mar. 2004

2 : approachable and capable of being asked a question I think it is important that you be an askable parent, so that he will know that he can come to you with any sort of question and that you'll give him a straight answer.— Ruth Westheimer, Chicago Tribune, 14 Dec. 1995
