I have no response to that.

Normally, when I see someone stumble/trip/fall, I have the urge to burst out laughing...especially if it's my college roommate or other assorted friends with reputations for being clumsy. In my more mature moments, I have the urge to rush to the aid of the unfortunate soul who has just seriously injured himself (or his pride).
But sitting outside Starbucks this evening I watched a woman slip and fall right in front of me.
I didn't laugh.
I didn't help her.
I didn't think or feel anything.
I just watched her fall.
After a moment, I decided my response was insensitive and I asked her if she was ok. By then other onlookers had rushed to her aid (and she was totally fine).
But what does it mean?
