Whether it's cause or effect doesn't seem to matter but being inhibited is a killer disease

A good start is to watch a video of Mike Leigh's stunning film Secrets and Lies

and realise that without 'what can't be said' Eastenders would run into the sand

What can't be said can't be said for fear that someone will lose out, or chicken out or worse still will be upset

There's the inevitable catastrophe, that god will send a thunderbolt or tell your mother or let the cat out of the bag or give the game away and down will come cradle and baby and all.

All this probably connects to our fear of criticism, fear of ridicule and of failure.
