Alice: Hey John, why are you so tired today?

John: I was up all night working on that big project for our client.

Alice: Oh no, that sounds tough. Is the project almost over?

John: Yes, I just have to finish the final presentation today.

Alice: Well, good luck with that. Let me know if you need any help.
