Observation of someone I know

It was a Chinese community gathering.The members were preparing for the lion dance in Chinatown on Feb 18. They were divided into 3 groups, one practiced lion dancing, one practiced drumming and the other kungfu. The lion dance group was in the front of me. The coach was teaching two students how to do lion dance. The coach was a little bit bald, in white and had a big stomach. The lion he was holding was black covered withbeads glittering in different colors. He was explaining the steps--each step should drop in the interval of the drum so the dancer should pay close attention to the drum. The dancers were listening to his explanation, both with their arms across their chest. Then the coach asked the drum team to drum. There came the drum. My attention shifted to the drum team. It was consist of five people--one senior grey head, one man in his 30s, three children (two boys and a girl) in 8-10. The senior grey head, Mr Hung, was the head of the team. He was explaining the rhythm to the children. But only the girl Maggie who was in a music group in school was listening. The other two boys were more like fooling around. Then Mr Hung asked the man Mike to drum. Mike drummed in a particular rhythm: a beat to the side of the drum every three to five drums. The drum was very loud. Once it started, all the voices were covered. I once wondered whether it would bother neiboughrs.
