Yesterday you tried to open the door for my boss as she was leaving the office, but she freaked out & locked it in your face. You were understandably frustrated, no doubt chalking it up to racism, as you said through the glass that you were only trying to hold the door for her. What you didn't know is that 2 weeks ago, our office was invaded by a mentally unstable homeless man who chased us out of the office; now we're pretty skittish about unknown men approaching the door & trying to open it when the office is closed. Door-holding is almost unheard of in this city (that's another rant), so your chivalry was completely unexpected. Thank you for your attempted kindness. Please forgive us for judging you wrongly in the split second in which she had to make the decision (fearing another attack) & for not apologizing immediately. She was freaked out & I was chagrined. When I went out to explain, you were gone.
