Why couldn’ t the man sleep last night?

W: Didn’ t you sleep well last night? You don’ t look very well.
M: In fact, I couldn’ t sleep last night because Martin was making so much noise. He should turn his radio down at night. He’ s so clumsy, too. He never does anything quietly.
W: Is it Martin’ s turn to cook the meal tonight?
M: Yes, it is! He should have washed the dishes last night too, but he didn’ t.
W: He’ s so lazy.
M: I’ m fed up with him. He left all his clothes and shaving things in the bathroom again.
W: If he cleaned his room and tidied the bathroom more often, he would be a pleasant person to live with.
