Hope you get answers for your knee. I’ve done cortisone for different issues and sometimes it works and other times it doesn’t. Did you have an MRI to see what’s going on in your knee? Sorry it stopped you from going to the event. I have a friend that I knew growing up who’s Mom is the grand daughter of a famous American First Nations Chief. She was taken away to a school to de-cultural her. These schools were all over America too - I was watching a documentary about them - awful what the government did.
