I dance because it's not groovy!

I was listening to one of my current favourite songs from Faye Wong (duet with Eason). Shean Wenn was dancing and shuffling her feet to the song.

Me : You like this song, don't you?
SW : No, I don't. 
Me : Oh? Then why are you dancing to it then??
SW : If I am dancing like this, it means I don't like the song. See? See how I am dancing?

Then another Faye Wong's song comes up. She stood still.

SW: Oh, this is my FAVOURITE SONG! See, I am not dancing. If I am not dancing, it means I love the song!
