I got on the elevator and just as I turned to punch buttons, I saw a nurse I know peel around the corner clearly headed for the car. Just as punch the open door button and they reverse, she reaches in to break the beam.
She barks 'just wave your hand in the door, don't you know ANYthing?'
Me: you can tell me what to do or how to do it, but not both.
That stumped Nurse Ratchet for @10 seconds . . . and made my day.
I like her, she's pretty cool.
