Also:
I wasn’t there, and don’t know the exact circumstances, but I think that in most situations like that, the boys should not offer to help and the girl probably would not want the boys to offer to help.
Seriously: She was able to get up, no? It didn’t take her more than 30 seconds to wriggle out from under, did it? There were other females in the area who could have helped if she really needed it, no? And most seminary girls would be much more mortified if the group of guys had come over to help her up, no?
Gimme a break.
On the other hand, I was driving a couple weeks ago and saw an elderly lady trip on a curb when a fire engine came by, and I stopped my car in the middle of the street and ran out and helped her up. Because that was a situation where I should help and where she’d want me to.
