Well, what an encounter and how awful.
That's built up resentment right there. So even when not in the encounter you are carrying all this around?
If you weren't then your reaction might have been different (I'm not saying that it could have been different to comfort AH and SS - I mean for your own well being).
So maybe just look at it as another one of those calls to take a look at how detached you really are and how you can shake off those resentments?
