What are you doing?

What do you think you're doing letting the loyalists into the castle?

Not doing one's work properly may be worse than not doing it at all.

I feel like I'm always doing nothing but doing chores.

You're doing good work there.

You are doing very well.

Hey, what'cha doing tonight?

I'm tired of doing busywork.
