Ivan: Well, OK.

Aldo: What's up?

Ivan: I was wondering whether you will go to Anita's farewell party tonight.

Aldo: Oops, I almost forgot about it.

Ivan: So, are you going to go?

Aldo: I don't think I can. I think I will be still working on my homework tonight.

Ivan: Too bad. I thought we could go together.

Aldo: Yeah, too bad.

Ivan: You have a lot of homework.

Aldo: Indeed. I was working on it too when you came at this time yesterday.

Ivan: Yeah, I remember. OK, I hope you can finish it soon.

Aldo: I hope so. Oh, by the way, send my regards to Anita.
