Just read a post about ‘one fell swoop‘ (actually one swell foop) from Seth Godin. That being, there is no such thing as one fell swoop. Life generally happens gradually. Except in hindsight. Hindsight can be very fell swoopish.
Puts me in mind of ‘the world ends not with a bang, but with a whimper.’ (I think this was T.S Elliot.)
