- He mockingly refers to them as "good friends" - when he knows that they are only his father's spies, sent to keep tabs on him.
- He evades their questions and gives them cryptic answers - refusing to engage with them in any meaningful way.
- He insults their intelligence - by making fun of their lack of understanding and their inability to keep up with his wit.
- He treats them as if they are beneath him - dismissing them with a wave of his hand or a dismissive comment.
In short, Hamlet's behavior towards Rosencrantz and Guildenstern is a clear indication of his contempt for them. He sees them as nothing more than pawns in his father's game, and he treats them with the disdain they deserve.
