It is a truth universally acknowledged, that when your mother full-names you – she means business
Allow me to demonstrate:
“Charles Phillip Arthur George Mountbatten-Windsor – I think you’ll find young man that those are my Crown Jewels. Return them to the Tower of London immediately or I shall set the Corgis on you!” (Circa 2011)
Your mother’s body language in this situation was always key. With an eyebrow raised and arms crossed – the death stare was employed. That was your cue to return her Crown Jewels / put down the hammer / take your brother’s GI Joe out of the microwave (even if he had decapitated your Tiny Tears).
Let’s face it – nothing else your parents said carried as much weight. You always knew
better:
Being told “No you can’t watch that” merely resulted in you screening the desired 18 rated slasher horror psycho chainsaw massacre hell-raising blood-fest at your mate’s house instead. You’ve slept with the light on ever since.
As a child, being informed that something was prohibited, only ever made it more beguiling. As such, any of the following statements would have, quite rightly been wholeheartedly ignored:
“Your father’s nail gun is not a toy”
“Calpol is not fruit cordial”
“Superglue, bleach and WD-40 are not fair weapons to employ in a water fight 
with your younger sister”
So, when stating the obvious didn’t work – your parents attempted reverse psychology:
“I really love what you’ve done with your jeans. How do you get the waistband to sit just below your buttocks in that way? I hope you wear them like that forever”.
If that failed, they resorted to outright lies:
My father used to tell my brothers and I “We’re nearly there” roughly an hour and a half into a 6 hour journey to Dorset. “I wonder who will be the first to see the sea?” he’d ask, midway through Luton.
I had an epiphany in my late teens and I didn’t like it. I realised my parents actually knew more than me.
Here’s some whimsical wisdomness, from older, wiser grown-ups. Show-offs:
