Post by occamA BBC News item this morning used the expression to describe the UK
government's attitude about <some issue>. It means "to do nothing about
a problem or a situation that needs dealing with."
The image I have is of a young person sitting, with hands tucked under
his thighs (maybe swinging this legs?) while doing nothing.
Is this a polite form of "sitting on his arse, doing nothing", or is
there more to it? Normally, there is an element of boredom associated
with sitting on one's hand.
I think your interpretation is too negative.
I was taught the expression when learning chess.
(by someone much better at it than I will ever be)
It means: don't do impulsive things that may look good
on the spur of the moment, but that you may regret later on.
In other words, take the time to take stock of the situation,
and produce a considered response, even if that takes more time.
So: prevent your hands, and so your intuitive responses,
from taking over from the brain.
And, don't let your opponent(s) tempt you
into giving the obviousand immedidiate response.
Don't allow yourself to be pressurised into immediate action.
Or in chess terms, think twice before taking a gambit,
