Read the excerpt from Act IV of Hamlet. Gentleman:
GENTLEMAN
She speaks much of her father, says she hears
There’s tricks i' th' world, and hems, and beats her heart,
Spurns enviously at straws, speaks things in doubt
That carry but half sense. Her speech is nothing,
Yet the unshaped use of it doth move
The hearers to collection. They aim at it,
And botch the words up fit to their own thoughts,
Which, as her winks and nods and gestures yield them,
Indeed would make one think there might be thought,
Though nothing sure, yet much unhappily. She speaks much of her father, says she hears

HORATIO
'Twere good she were spoken with, for she may strew
15Dangerous conjectures in ill-breeding minds.
GERTRUDE
Let her come in.
Exit GENTLEMAN
The GENTLEMAN exits.
(aside) To my sick soul (as sin’s true nature is)
Each toy seems prologue to some great amiss.
So full of artless jealousy is guilt,
It spills itself in fearing to be spilt.
