I am happy that she gave me a nice comment on our music.

I promised today's tutor to let her know when our new album will be released.

We talked about the power of music.
She seemed to like our songs and gave me a lot of applause.
I was flattered. ;-)

Her nephew is also a guitarist and is living in Japan!
