무릎을 다쳤어!

My poor knee... I don't how it was injured but it hurts so badly this morning that I have to go see a physician after my morning classes. Dearie was so puzzled that I did not know I have injured myself without doing anything...

 The physician said I had a bad muscle pull and it could be due to my sitting or walking etc. I guess I could have strained it while packing 8 boxes of materials for the coming conference on Monday. 

 I don't know how I'm going to setup my booth tomorrow but I will try...
