dance is not equal to play

"Wanna come out play?" they always ask so when they are going clubbing. I supposed I am not a clubbing person. But I do like dancing.

They say that I am not like me when I am dancing. R said I hide this part of myself. Maybe it wasn't me, or maybe it is the real me!? I remember that a singer said something like, he cant speak well except when he is singing. In the musical Billy Elliot, it also addresses similar idea. "...just like electricity... I feel free..."
(I dont remember the lyric exactly, but, u know.)
Sometimes you just feel free when doing particular activities... you are really into it, really enjoy it.
