.  I'll bet that someone said, "Are you okay?" about every 0 minutes. When we dropped something, stumbled, almost stepped on a nail, tried to lift debris that was heavier than we expected, got a drop of sweat in the eye, cough from the plaster dust, even had trouble getting a glove off so we could get a sip of coffee or water, there was an unconscious "oof", "woops", "oo", "uh-oh" from the 'victim'. No one really needed help or got hurt, so it was always, "Fine, thanks," but I had to laugh because of this thread.
