Was it just me who used to absolutely HATE it when their parent said 'im not cross, just disappointed'.
It was so much worse if your mum and dad were disappointed rather than angry. That's when I knew I'd fucked up as a kid!
Another, which of course I now use myself is counting to 3. What do people actually do when they get to 3? I don't remember my parents ever getting there and I panic that one day one of my DC will push me to the dreaded 3 and I'll be forced to show my anti climatic hand.
Any others you remember from childhood that everyone else seemed to know too? Or that you stole from your parents & now use on your own?
