Need to write a narritave of macbeth and lady macbeth preparing to attend banquo's funeral. no idea where to start or how to proceed with this.

Onstage stands a table heaped with a feast. Macbeth and Lady Macbeth enter as king and queen, followed by their court, whom they bid welcome. As Macbeth walks among the company, the first murderer appears at the doorway. Macbeth speaks to him for a moment, learning that Banquo is dead and that Fleance has escaped. The news of Fleance’s escape angers Macbeth—if only Fleance had died, he muses, his throne would have been secure. Instead, “the worm that’s fled / Hath nature that in time will venom breed” (3.4.28–29). Returning to his guests, Macbeth goes to sit at the head of the royal table but finds Banquo’s ghost sitting in his chair. Horror-struck, Macbeth speaks to the ghost, which is invisible to the rest of the company. Lady Macbeth makes excuses for her husband, saying that he occasionally has such “visions” and that the guests should simply ignore his behavior. Then she speaks to Macbeth, questioning his manhood and urging him to snap out of his trance. The ghost disappears, and Macbeth recovers, telling his company: “I have a strange infirmity which is nothing / To those that know me” (3.4.85–86). As he offers a toast to company, however, Banquo’s specter reappears and shocks Macbeth into further reckless outbursts. Continuing to make excuses for her husband, Lady Macbeth sends the alarmed guests out of the room as the ghost vanishes again. Macbeth mutters that “blood will have blood” and tells Lady Macbeth that he has heard from a servant-spy that Macduff intends to keep away from court, behavior that verges on treason (3.4.121). He says that he will visit the witches again tomorrow in the hopes of learning more about the future and about who may be plotting against him. He resolves to do whatever is necessary to keep his throne, declaring: “I am in blood / Stepped in so far that, should I wade no more, / Returning were as tedious as go o’er” (3.4.135–137). Lady Macbeth says that he needs sleep, and they retire to their bed. I hope this helps you out..
