history: I had to leave the house for a bit, while I was gone my kids did all their chores.  I figured they would just goof off. I had to leave the house for a bit_comma_ before I left I gave my kids instructions on what I wanted them to do around the house. Did they follow your instructions_comma_ or did they do their own thing?
current: I figured they would just goof off.  However; when I returned all chores were comples.  I was pretty impressed.
next: Wow!  I didn't expect that answer from you!  That must have been a great surprise!
