Ballroom dancer Trisha Pérez Kennedy says that “normally, her partner’s touch helps communicate the next step in a dance combination. ‘We use the strength of our bodies to speak to each other,’ she says. ‘It can be as subtle as the pressure of his hand on my back to help me know what will happen next. When you’re dancing on your own, you don’t have that guidance keeping you in check. You have to own all of your technique.'” – Wall Street Journal
