Finish up

"Looks like our tutoring session is finished." you tell Cao as you look at the small clock on the nightstand.

"Yes, but I'm quite glad and yet surprised we took it to the next level, John. Are you sure we'll continue doing things like this?" Cao asked.

"Maybe, but hopefully it'll happen again." you reply with a smile.

Your tutoring sessions with Sun Cao were rather successful, showing her high intelligence and resourcefulness, but you even gave her extra credit by 'extending' your sessions.
