That sounds awful. I'm sorry you had to be a party to such an event. Even if there were all these other older and more experienced people who should have acted intelligently, it sounds like you're still feeling guilty that you didn't do better. It's hard to realise that in most situations you do have to trust that in your instincts, instead of being able to think that all these supposedly more senior and responsible people actually have a clue... It shakes your faith in people and your sense of security. I'm sad that you had to go through that.
