A club. Anything can happen and no one really cares what you dance like. At home. Your bro or sis might walk in though on you. My sister has always done that O.O School dance. Have fun with your friends. Dance like you're drunk. Do whatever. A store. People might look at you like wtf? But who cares. They don't know you.
Home is the best place to dance any type of dance like freestyle. You will be able to exercise the comfort and privacy. It is also the place where you will be comfortable to practice your favorite dancing style.
