3. Boiling water is dangerous

As an example of logic (common sense) think about this situation

You see someone about to put their finger into a cup of boiling water what does your logic tell you to do?

• You know that boiling water is dangerous
• Decision - you give a warning to the person not to put their finger into boiling water.

A parent will use this kind of logic all the time as their child may not understand the rules yet, for example

‘Don’t play with matches’,

‘Look right and left before crossing a road’.
