The thing about having any sort of relationship – business, social, personal – on the internet is that unless you meet the co-respondent you have no real idea of where they’re ‘coming from’ as in their true intent. Words are cheap and don’t actually convey much of a message except the most superficial and outer meaning of the words used – as learned in school. On the internet you don’t get to see or hear any of the voice tones, body language, facial expressions, smells including levels of perspiration, or any of the actual vibrations coming off the person as they talk. All of which give the recipient clues as to the root intention of the speaker and more clues about his/her character.
Like when I was in Turkey recently – after paying for something in the local supermarket the cashier gave me change of 6 TL – all of which was in coins. She did this very deliberately and for the entire duration looked at me straight in the eye and with great intensity. I thought “What’s going on here then?”
The moment got lost until I got back to the the place I was staying and found I’d been given shed loads of English 10p coins – all totally worthless out there, of course and with much less monetary value than the same sized Turkish coin which this was supposed to replace.
I wouldn’t have got any of that information on the internet.
