I taught my brother to play the piano at home every week. He had a piano teacher who would leave some homework and songs for my brother to practice, and sometimes he doesn’t know how to play some songs and needs some help from others. I voluntarily helped my brother in various ways. I first showed him how to play the song, then coached him over and go through all the new songs with him. However sometimes my brother doesn’t follow my instruction since he was kind of in the mood. I should be more patient and kind while coaching him, and I shouldn’t be rushing the practice hour although I had a lot of homework to do
