Bonny: Are you mad?! You told the repairman to come tomorrow?! 
Mary: What's wrong about it? He says he needs only a couple of hours.
Bonny: But nobody will be there to let him in.
Mary: I will. I'm taking half a day off.
Bonny: Well then...
Bonny is angry with Mary that she asked the repairmain to come tomorrow as there will be noone at home, but it turns out that Mary is taking half a day off.
