S.H.
I am glad to hear your daughter is alright, and I would make sure to speak with her troop leader regarding supervision at future events. Yes, accidents do happen even under the best of supervision, but you also want to know that your daughter will be safe.
Case in point, I was a chaperone at our council's annual dance for the girl scouts last year and was shocked at the "craziness" going on there. Girls were running wild, one girl even got her teeth knocked out b/c she collided with another girl. All the moms and leaders just stood around until finally there was an announcement made AFTER the accident that there was to be no running. I am not letting my girls go this year.
And as for your response from KK, you are absolutely rude to say such a thing. You have got it backwards sister, it is oblivious parents such as yourself that maintain a "kids will be kids" attitude and children DO get hurt.
Best of luck to you in your future outings!
