what did you get up to ...?

I say 'I want to know what you did at that time (e.g. last night).'

I think like this: I want you to think I feel something good towards you. I think you did something good last night. I want you to say it.

I think you will say something like “I did something good.”

I can feel something good because of this. You can feel something good because of this.
