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.
