Look, But Don't Touch
This is a familiar warning. In the gym, to ensure participants are 2 meters apart, the machines in between have these signs - "Look, But Don't Touch." I suspect children hear this the most. Some things are like magnets, and there is a longing to touch, maybe to see if it's real, or how soft it is. Or, in the case of candy, well...they already know the taste. That's when parents may regret their child having seen it at all!
