Answer:
Polonius sends Reynaldo to spy on Laertes by pretending to send him to deliver a letter and some money.
This shows that the master and servant have a confident, full trust on each other. Polonius trusted him enough to send him for an intimate family affair.
This act shows that Polonius seems to have a hold, or even tries to control, what his children do, and even over his servants, who are all 'supposed' to obey his commands.
Explanation:
In Act II scene i of the play "Hamlet" by William Shakespeare, Polonius had decided to send his servant Reynaldo to Paris to deliver some money and also a letter to Laertes. But the real reason for this trip was to send Reynaldo to see if Laertes is really doing what he is supposed to do or he's just wasting his time around. In simple words, Reynaldo was sent to spy on Laertes by his father Polonius.
This shows that the relationship of Reynaldo and his master Polonius was a relationship of trust, true and of full confidence. Polonius seems to trust his servant with full confidence, sending him on an intimate private family matter.
This act of Polonius sending someone to spy on his son shows that he did not trust his son to be on the right path. Also, it shows how much authority he can wield over his children, and also over his servant too.
