‘Tis in my memory lock’d,
And you yourself shall keep the key of it.

– William Shakespeare

Hamlet, Act 1, Scene 3. Ophelia assures Laertes that she will follow his advice. Has has counseled his sister to spurn the romantic advances of Hamlet. The theme of male control comes across strongly Ophelia’s words, in which she paints an image of handing her brother the keys to her mind and memory.
