If the duke continue these favours towards you, Cesario, you are like to be much advanced: he hath known you but three days, and already you are no stranger.

– William Shakespeare

Twelfth Night, Act 1, Scene 4. Valentine tells Cesario (Viola) that he is already a big hit with Orsino after three days on the job, and should go far. Perhaps foreshadowing more than a master-servant relationship, even lovers?
