You spoke very well today. I enjoyed our chat on your famous homemade apple cake. I saw pictures on Facebook and it looked delicious. I look forward to more English expressions in the next class and if there is anything you want to query in English don't hesitate to ask me. See you after your business trip.

Excellent lesson today. It was lovely to see you again and even though I hadn't spoken English with you for over a month you blew me away today. I look forward to teaching you again soon.

Nice session, I learnt how to wish my sister "happy birthday" in Russian too! :)

I had a great time talking to you, I laughed a lot too!
