A young girl shared a wholesome moment with complete strangers in a park when she started dancing to a street musician and many of them started to join in, copying her every move. In the sweet clip, four-year-old Cala can initially be seen approaching the musician near the Royal Palace of Madrid, in Spain, her father, Francisco, capturing the moment on video. But then, as Cala started to put out her arms and spin to the track, a few passersby decided to join in. A few others then followed in those onlookers' footsteps... and then another... and another – until, eventually, there was a small group of people copying Cala's every move. The moment took place on February 15, and Cala's older sister, Amelia Reyes, 18, later shared the video online, where it received more than three million views.
