Leading, with a pencil, 8 year old Sophie through the right hand of a new piece tonight, I skipped over a tied note.
Ate the end of the phrsae, I stopped and drew a light circle around the notes, pointed to the tied note and asked, "Why did I leave out this note?"
Sophie peered for a few seconds then announced triumphantly, "Because it's a smiley face."
Looking closely, I saw the the combination of circle, notes and tie line had indeed created a smiley face.
I went with the flow on that one. A fiver says that in five years time, Sophie and I are still referring to tied notes as 'smiley faces'.
