It's time to move past King Hamlet's death. There are many other matters to deal with
King Claudius (Uncle)
Queen Gertrude (Mother)
why she, even she--O, God! a beast, that wants discourse of reason,Would have mourn'd longer--married with my uncle,My father's brother, but no more like my father. Than I to Hercules: within a month: Ere yet the salt of most unrighteous tears. Had left the flushing in her galled eyes,She married. O, most wicked speed, to post. With such dexterity to incestuous sheets! It is not nor it cannot come to good: But break, my heart; for I must hold my tongue.
"Why are you still upset about king Hamlet's death?"
Also in King CLaudius' inauguration Speech:
and we here dispatchYou, good Cornelius, and you, Voltimand,For bearers of this greeting to old Norway;Giving to you no further personal powerTo business with the king, more than the scopeOf these delated articles allow.Farewell, and let your haste commend your duty.
