S.H.E - 天灰Tian Hui (Darkening of the Sky)

This song describes my mood from yesterday afternoon till now.. My sky feels so darkene now..

Why do I have to be so nervous? I am shivering from the time I waited in the room till I was in the car..

I felt my attempt in doing vertical, parallel and directional change (which is supposed to be best)..

Why????
