Toward the end of Friday’s workday, I stepped outside the office to take a break. I wandered aimlessly around the parking lot for a few minutes and headed back to the door. In the twilight, I could make out what looked to be one of my coworkers leaving the building. (My vision is a little haggard in semi-darkness.)

As she approached, she said, “Hey.”

I said, “Hey” back.

“Oh, I’m talking on the phone,” she exclaimed, holding up her device. “I’m really not crazy! Haha!”

But I, talking to the person standing right in front of me, must be.
