The conversation between Lady Macduff and her son is comedic because he provides a commentary on her life that is far beyond his years. His mother's surprise at his bluntness, when he turns the conversation around onto her (she says "what wilt thou do for a father?" and he replies "nay how will you do for a husband") she is surprised and the mood is lightened a bit from their worry and anger about Macduff's leaving. The boy is witty and bold, which makes his mother (and the audience) laugh.
QUESTION: Satish was standing on the balcony watching the last rays of the sun. Loud and angry voices below distracted his attention. He ran down the stairs to see what had happened. He seen a guy yelling at a lady that she had cheated. Satish seen the girl crying saying “I didn’t do it he’s just a friend” he yelled at her “I seen the messages why would you do that to me” she ran. Her husband went after her yelling that he’s going to take her to court and get lawyers. She begged him not to do this. Satiah quickly ran over to her and said if she needed anything she stated laughing and said “yes, a lawyer” he called his friend and helped her. 2 weeks pass by and she lost the case because In did she did cheat he took one of the kids Nd she took the other they both had to switch after a week. The end sorry if this isn’t good I love tea so I ofc had to add the tea
