Yes, me too.
OK, let's do that.
I've got a meeting now.
Call me on my mobile.
It's really nice.
Yes, good idea. Let's go there.
No, I don't think so. I'd rather take the train.
I'm sorry I can't. I need to finish this report.
I need to do the housework.
What do you want to do now/tomorrow?
I'm tired and sleepy, I need to go to bed.
I'm not sure what I want to do.
I might go for a walk.
Finally I finished my exams today.
Great, thank you very much. 

I have got something to do.
How do I get to your place.
