I'm not responsible for the actions, behavior, or whereabouts of my close relative or friend not necessarily a brother (Often used to express frustration that such responsibility is assumed: Of course I'm disappointed that Travis got arrested again, but I'm not my brother's keeper. • How should I know where Mary is? I'm not my brother's keeper.  thefreedictionary.com); you are not responsible for another person's doings or whereabouts (Biblical: Fred: Where's Robert? Jane: Am I my brother's keeper? • Jill: How could you let Jane run off like that? Alan: I'm not my brother's keeper.) |
