What we are talking about here, is leaving your children unprotected ,defenseless, in unlocked accomodation, whilst out boozing.
Since when has going to a restaurant for a three course meal where wine is served with the meal ever been thought of as a night out 'boozing' by normal, reasonable minded people? The fact that you have to wildly exaggerate speaks volumes.
Whether you like it or not, there are hundreds of thousands of parents who have left their children asleep and alone in their rooms and gone out for the evening whilst on holiday. Some still do.
Anyone who thinks that not one of those hundreds of thousands of parents have every left a door or a window unlocked either by accident for design, is living in cloud cuckoo land IMO
Some of them don't go back to check on their children at all
themselves - from the time they leave until they return.
As far as I know - none of them have ever been charged, arrested, or convicted for doing that whilst on holiday.
If you know differently then please provide the evidence?
