Hello everyone! I'm thrilled to know I've entertained strangers on the internet! This took place last July, actually. As for how I did this, I'm just incredibly clumsy and landed on my left knee at just the wrong angle. To make matters worse, I was on vacation in Williamsburg VA and it was 110 degrees every day, and I had to walk everywhere with an black foam knee immobilizer that went from my ankle to my thigh. My proudest moment was when an 80 year old man had to help me down the stairs. My physical therapy paid off, and I'm back to normal, though apparently I'm a bit knock-kneed and need to be more careful. Thanks for all the good wishes!
