Scenario:-

Our music leader is holding up ‘Stop’ and ‘Go’ signs in the chorus of As a Child of God.  The teachers had just been handed their own copy of the song and were looking down at the words rather than look at the music leader.

The children were all paying attention, the Stop sign was held up and one teacher sang through the ‘stop’, completely oblivious until the little person next to the teacher gently tapped them on the arm and piped up “Excuse me *insert name*, you sang through when you were supposed to stop”.

The teacher glanced up, had a quiet chuckle and exclaimed “Oh, I must have the wrong glasses on today.  Silly me!”.
