All of you must have read shakespear's work, "The Merchant of Venice."
There is a scene wherein Portia disguises herself as a lawyer to save her husband from Shylock and once done, she is requested to ask for something as a prize and she asks for the Ring that her husband is wearing. When he refuses, Protia says this: "You taught me how to beg and now you teach me how a begger should be answered."
What is the meaning of this sentence in that context.
I think this occurred after she saved her husbands life by pretending to be a lawyer and winning the judgment saving his life. Her disguise is so complete that he does not recognize her. I don't think Portia was a very nice character so she decided to test her husband and ask for their wedding ring as a prize for saving his life.
This line is her way of putting her husband to a severe test by making him feel guilty. He owed his life to the actions of the lawyer(Portia in disguise) so he felt that he could not refuse eventually.
