When I got to my office building one morning last week, there was an older man waiting at the elevator bank who had already pushed the "up" button. As I walked into the lobby, the elevator closest to him arrived, but he was facing away and didn't turn around.
I made some comment as I snuck behind him and held the door, something along the lines of "Well, look at that, you called it right to you." It was my way of alerting him without pointing out that he missed the DING! and the little red light.
He chuckled kind of awkwardly and said, "Oh! And I didn't even hear it!"
Of course I replied with, "They can be hard to hear sometimes," and we had a pleasantly uneventful 45-second ride together.
When he stepped off at his floor, I wanted to send him on his way with a little have-a-nice-day farewell. But, in light of recent events, I didn't know whether to say, "Have a good one," or . . . like . . . "HAVE A GOOD ONE!!"
So I kept my mouth shut.
