Answer:
Erratic(Unpredictable, unstable,etc.) Behavior
Step-by-step explanation:
Within the castle, Claudius and Gertrude welcome Rosencrantz and Guildenstern, two of Hamlet’s friends from Wittenberg. Increasingly concerned about Hamlet’s erratic behavior and his apparent inability to recover from his father’s death, the king and queen have summoned his friends to Elsinore in the hope that they might be able to cheer Hamlet out of his melancholy, or at least discover the cause of it. Rosencrantz and Guildenstern agree to investigate, and the queen orders attendants to take them to her “too much changed” son (II.ii.36).
