Sure! Here’s the completed dialogue:
A: I'm so sorry I'm late. I missed the bus.
B: But you're always late.
A: I'm sorry.
B: Why don't you leave home earlier?
A: Look, why don't we order? I'm really hungry.
B: No. I don't want to stay here any more.
A: OK. Why don't we go for a walk? I can get a burger or something.
B: I don't like to go for a walk. It's been a long day and I'm tired.
A: Listen. I'll take you home now. And tomorrow I'll make dinner for you at my house. What do you think?
B: OK. I suppose that way you can't be late!
