life was a NOT

when I look back at my childhood, I realised that the most uttered word was :

do NOT climb the trees
do NOT answer back
do NOT play under the rain
do NOT go near strangers
do NOT touch the glass
do NOT forget to take your lunch
do NOT go out at midday
do NOT etc
do NOT...
NOT

why NOT ? perhaps that was the best parenting method that suits kids of my generation.
or maybe, saying NOT is the easiest way to convey the message (let me think, did I take heed?? degil, degil)
mmm... I wonder, NOT ;)
