I can always remember the day when I fell out with my mum, about aged eight.
Exacting my revenge to counter the unfairness of how I perceived it, I twisted one of the slats of her Venetian blinds, being the main ones in the living room. She walked in and seen it. I thought I was in deep, deep shit. Rather as be in deep shit she said something like; (I can't remember exactly what she she said) "I'm disappointed in you". I knew that she knew that I knew what I had done was wrong and vindictive. She had to say say nothing more as I really felt shitty and knew I had hurt her in a way that put the whole responsibility on me. I acted like a dick. She let me stew on my own juice and I learned a valuable lesson.
Dangerous ?
Maybe not but I think it ties in with the flavour of the thread.
It certainly taught me a valuable lesson.
Actually Keasy, the very same thing happened to me, some eons ago.
My Dad discovered, shock horror, that me and my bro and sis were smoking on holiday with them in Spain.
He found out and all he said was 'I'm disappointed in all three of you.'
That was it and he left it at that, but it had it's effect in the sense of the look and the tone
Unfortunatley, it didn't stop us smoking , which I wish it had...............
