In the subtle differences category I have a real life example of my own. Well I have many, but one happened the same day you posted this. It should be noted that chat and posts like this drasticaly increase the confusion because of the lack of non-verbal cues as to a words meaning.

My example happened in an IM session while helping a fellow programmer debug. At one point he said "i can't be bothered to fix that", which reading now doesn't sound offense, but at the time, in the context, it sounded to me like a great insult. I had spent my time helping him and then he suddenly can't be bothered. I see it as a good example of this law in work because even now I don't see the insult. Communication is such a treaky beast, in my head this seemed like a great post and now it has dwindled to nothing more than a rambling.

Just my 2 cents as usual.
