I took him to one of our local trails because he wanted some "tips" for an upcoming adventure race. Unfortunately the "tip" was how to ride a small drop (@ 8") at a creek crossing and avoid the root and the rock. I showed him a couple of times how to do it, gave him clear step by step. At the last minute, he panicked and grabbed a handful of brake and went down! He knew he panicked and didn't hold any resentment (as far as I know), but I felt horrible for a long time. Luckily, he healed quickly and competed in the race. I haven't heard from him in a while, but hopefully still riding.
