I have not been bothered by square dancing, but I have witnessed group fights, alarmed the 110, and seen the farce performed by others. There is a small contractor especially love ballroom dancing. Probably burned with money. He plainly switched women and hung out among the warblers. When he and Junior were having a good time, Junior showed up to wreak havoc and hit Junior, his sharp nails scratched each other's faces, and they wrestled together. The men tried their best to pull the two men apart, and had no choice but to report it to 110.The whistling police car came and solved the matter. But the onlookers, in three layers outside three layers, everyone came to watch the ugly farce, this is why it is bitter.
