Answer:
Hamlet is Shakespeare's famous revenge play. In the play, Hamlet is frustrated by the fact that his uncle married Gertrude, Hamlet's mother, right after his father's death.
In Act I, Scene II, Claudius asks Hamlet why he is still mourning for his dead father and wearing black clothes. Hamlet replies that his sadness is so great that it is not even reflected in his appearance. Claudius insists that all fathers die, and Hamlet should not mourn for too long. He also reminds Hamlet to consider him as his father from now on.
Claudius is, obviously, trying to balance the sadness over his brother's death with happiness over his new marriage. This is not natural at all, and Hamlet clearly sees it. He considers Claudius' marriage to Gertrude as an incest. Hamlet wants to mourn in isolation, and does not want to accept the fatherly advice he gets from Claudius.
