We work in a building with 5-6 different companies sharing 3 elevators. One day, one of my male colleague and I entered into a lift which was 3/4th filled. By mistake, my male colleague's forearm touched one of the women and he adjusted immediately. But, she responded rudely to him and said something nasty. My colleague and I were not happy with what happened. Yes, he was hurt and he said the same after coming out of the elevator.
She is not a colleague and we have no idea which company she works for.
I was wondering, what could I have possibly said to him to pacify him or infact, to that woman?
