Practiced Euphonium with high school students

Today I practiced Euphonium with high school students at their school.Because our brass band club were asked them.I went to there by train.Soon I got at there we play in concert.It was very fun!!Usually our brass band don't have coach so we should practice our self.But today I learned from high school teacher so I enjoyed learning.It was very good for me.But it was very hard practice so I was very tired… And when I went to back home, train postponed theirs departure by falling rock.So I should wait for one hour and half… I was very tired!
