John was beaming. "Donovan said you're a freak."
"Damn!" Sherlock looked very put out. "I was being particularly civil to her."
"Exactly," said John. "Acting out of character. Completely unnerved her." Sherlock glared at him.
"Been quite a morning," John continued. "One witness asked where your hat was, another was a fan of my blog and that new DC assumed we were a couple."
Sherlock scoffed. "Don't look so smug. Before we left, I guessed your new password and Mrs Hudson reminded me she wasn't our housekeeper. When we got here, the officer standing guard said I looked taller in photographs and three deductions in, you automatically called me 'brilliant'."
Lestrade signalled to Sherlock and Sherlock glanced across at him. "Right," he said, "I'll go and talk to the suspect."
John looked at him. "You're not going to cheat, are you?"
Sherlock smiled. "I'll just be my normal self."
As the detective walked away, John knew it was all over. Anxiously, he watched as Sherlock questioned the man, the suspect's irritation unmistakably mounting. When the punch eventually came, John flinched in sympathy but Sherlock had ducked and Lestrade quickly restrained his assailant.
Sherlock turned towards John and triumphantly waved his list in the air.
John sighed.
After the Cluedo debacle he should have known better than to try Sherlock Holmes Bingo.
I think (if I've understood you correctly) that I'm going to have to disagree with you again. I don't believe you can read anyone's mind looking at their body and behaviour. Yes, people give themselves away a little but most adults hide what they think. Even if you observed a person continuously throughout their life, you could never be sure how they were reacting internally to a situation.
Even when we know a person well we're really just constructing our own version of them within our own brains. We're all strangers to one another. And we can never truly fully comprehend our own minds, though admittedly the older you get, the less your mind can surprise you.
I don't believe language is simply a way of recording thoughts. It's the only way we have of attempting to share thoughts with others. And even then it's only an attempt.
I'm not sure about the idea of a "filter" being put on our minds. I'm not certain society can alter what happens in an individual's mind. (Maybe in the young but not permanently.) I'm not even sure society can truly alter people's behaviour. I think mostly people do exactly what they want and most of the time it just happens to coincide with the law and morality.
(Btw, are you interested in Sherlock or were you just passing by and thought you'd leave a comment as there weren't any? ^^)
