When my son was small - about 3 years old - I was afraid he would rummage through my craft bag and impale himself on various painful crafting devices. I took him aside and explained that he shouldn't touch the scissors or needles because they would hurt him.
He looked at me and said "Sizzies and Neenos hurt?"
"Yes" I said.
To this day in my home, we call scissors 'Sizzies' and needles 'Neenos'. It reminds me of when he was small and trusting and listened to everything his mother told him.
Now that he's 12, that seems like a long time ago.
