Is Rosencrantz and Guildnestern true friends of Hamlet ? Explain ( Discuss : how is this an underestimation/ misinterpretation of Hamlet on Claudius part? )

In my opinion, the men are chums.... acquaintances..... school friends, not true friends. Claudius underestimates their influence over Hamlet, as well as their dedication to their task. Note, it doesn't take ling for Hamlet to find of the true reason they've come..... the fact that he asks so quickly speaks to the kind of friendship between them.
