Dear student,
 
I hope you've had a fantastic day! Thank you for always giving me the chance to help you practice and improve your English skills, and share fun times! I hope you've been well. 

Today, I'm notifying you of my new available lesson times. I will be available on Sundays from 10:00 a.m. - 12:30 p.m., and again from 3:00 p.m. - 6:00 p.m. JST. 

The reason for this change is that there are a few other projects that I'm working on, and I would like to have more time to do them. 

I will also be sending out an update on the projects as I work on them, and you can check them out if you are interested.

Thank you very much for your time, and for always learning with me once again. Have a wonderful rest of the day! 

Happy learning, 
Brian
