IF the combined common sense of the girls caught on video behaving so aggressively at a Bournemouth shop were placed on one side of a set of scales and an empty bag of nothing on the other, which would be the heavier? I could take a guess.

The sad irony is that the girls who were actively involved in that unsavoury confrontation probably thought of themselves as pretty grown up.

And that is a bit pathetic when just about everyone else would see the behaviour they showed as the opposite. It was nasty.

You have to wonder what those teenagers’ parents will think when they see the video on the Echo’s website. Despair? Aghast? Certainly not pride.

Will the girls care what their families think? They certainly won’t give a monkey’s about what I think. Or care about how the shopkeeper feels. After all, caring about what others think and feel is what adults do.

Perhaps some of the girls filmed behaving so unpleasantly will look at the video on the Echo’s website that shows their grimly snarling antics and put on a display of bravado to try to impress their mates. They may be keen to explain and defend their behaviour. But I hope that one or two will look at it a second time when on their own and reflect on their behaviour. Scales, of course, cannot weigh sense. Just justice.
