Bee,
I've made mistakes that have caused long term injuries. That is just a part of this game. Some have been pure stupidity on my part, some just bad breaks. All with someone around. An extra brain or two around is a big deal.
Experience is suppose to teach us the risk reward equation. Sometimes we just brain cramp...I did it a few years ago glissading off Baden-Powell on too thin snow, in almost the same exact spot I severely sprained an ankle about 10 years prior doing a glissade with crampons on.
