This point is ringing rather clearly right now as I have just finished reading "Double Fault" by Lionel Shriver, which is a story about a young couple, pro-tennis players and their marriage. Not really up my alley, yet so much of the conversational text urges out dust-bunnies buried under tonnes of rubble.
It was an easy read - 300-something pages done in two nights, simply cos I could understand why Willy (the female lead) could get so stuck in her rut of self-destruction using deadly poisonous language (words chosen and presented in tones precisely meant to stab like a steak knife through the heart), and Eric (her book husband) eventually wore down in defeat.
While I am not an expert in the female psyche, I can say for sure this: Once an idea is rooted in our minds, there it'll stay.
Which is why we don't do the things we used to do anymore: like ask questions, verify information, ring up hotels to cross-check the alibi, or pick up the phone and call.
Cos there is simply no purpose in it: it wouldn't set things any more right than it is already wrong. And again said ~ once an idea is rooted in, there it'll stay.
As I said before ~ I have my own conclusions and my own reviews. And I'd rather be proven wrong (like buying this book!) than be proven right.
