I was getting a pillow for my mom who is in hospice care and as I went I bashed my knee on a piece of furniture so hard that I had to sit down and moan in pain and later it became red and probably will develop a bad bruise so my practices, many of which I do standing up and dancing, had to be changed, so I tried the new way of doing them sitting on a chair and to my surprise I thought they were better, so once again it has been shown to me that accidents and unintentional occurances sometimes are the best things that can happen.
