I have training in trauma and related EMT situations. People do not respond the same...and may not be able to behave like I think they should. Every situation is different, but the things presented earlier in this subject apply to almost any type of crisis. I have used them many times in the past with varied results. The same can be said of classroom situations. My best thoughts have been based upon one thing: consider the situation, and know your limits....especially when you don't know the person with the crisis and/or what their limits are.
Don't make it worse.
