我的中文英文基礎都不好,作為交流工具勉強過關,作為語言藝術,就一文盲 :))
Your knee still bothers you? Did you try physical therapy? Good ones really work. I injured my right shoulder once from playing softball. I went through a 3-month physical therapy session. And it's almost 100% now. It used to give me a sharp pain whenever I accidently trwisted my arm at an certain angle.
