As a parent, you are always reluctant to leave your children alone in a car. Do you duck into the service station to pay for petrol if your baby or toddler is sound asleep?
It sounds simple and reasonable, but it's actually illegal.
In Saturday's situation, the mother was well within her legal rights to allow her 14-year-old to look after her 4-year-old alone in a car because the legal babysitting age is 14. Besides, this is broad daylight in a busy carpark.
The children were not hurt but are understandably shaken. This is not going to be something these little ones forget in a hurry and potentially there could be lasting and damaging memories.
My thoughts go out to the children and their mother as this was a completely unforseen set of circumstances - one which certainly makes you think twice.
