Dear Mr./Ms. Hendra Milan. Best regards.
The cherry blossoms were in full bloom and the weather looked like spring. How are you getting along?
Now, the concert of the guitar teacher I am studying will be held on June 10. This time, professional guitarist Minami Yukari — the teacher's friend — will participate in the performance as a special guest. For details (note 1), please see the attached leaflet.
I know you're busy, but if you can attend, I'll be very happy. In addition, because the number of seats is limited, if you can come, please let ME know the number of people by email or phone at least one day in advance. I will have the entrance ticket ready at the reception desk. There is no need for ticket money.
The days of large temperature differences are still going on, hope you take care of your health.
Regards — April 3, 2013, Ooyama Haruki.
