It's easier when we are alone. That way, we can sing with all of our enthusiasm, and shimmy our bodies however we please. Without allowing for such a musical expression on some kind of a regular basis, no matter our age, it seems to me that we live our lives "in check;" properly restrained and composed, but missing out on a piece of freedom.
It's a primal thing to let go. Let's give ourselves permission. Let's crank up the tunes and get our bodies moving. It's heartening. It's joyful! And it's fun!! :)
I sing along to my favorite songs and dance with joy to the music that moves me.
