We are sorry about the class on July 23 that we have an unexpectedly urgent issue so we can not get in your class today. However, can we cancel about the class? We would like to confer with Akiko when she comes by all lessons and all questions which we don't clearly understand. Although, Can you send us the material of the 23 July class? We want to study before Akiko comes.
Thank you for everything which you have teached us.
