But say after a while I feel like these gliding movements just aren't enough to fully express myself. I have to enlist the more versatile angular movements.

但是过了一会儿，我觉得这些滑行动作不足以充分表达我自己。我必须争取更通用的角度运动。

Just the hand going. Waving my hand from side to side — it's a type of gliding movement, one that occurs when one flat bone surface glides over another.

只是手在动。左右挥动我的手——这是一种滑行运动，当一个平坦的骨骼表面滑过另一个时发生的。
