I used context in the conversational sense.
When two people who prefer to use a high-context conversation format talk to each other they will both dance around the point always, neither ever quite stating the point, each expecting the other to follow unspoken elements of the conversation as a matter of course. I'm only like 2/3 high-context, but I am strongly in this half of the ballpark.
Here is a high-context conversation in bold, with a more low-context version in parenthesis, and bracketed commentary for clarification on the differences between them:
"My cousin is coming over." (I am excited about my cousin visiting.)
[in high context, the excitement should be read from body language or more importantly simply inferred by the fact that the person mentioned the event at all*]
"Oh, I am very happy for you." (Really? What's the occasion?)
[in either case, these are ways to say "tell me more,' but direct questions are rude in HC]
"We always have a good time." (It's just a visit. Don't fill your head with unnecessary details, dude.)
[the first is not necessarily a conversation closer, however it IS a way of pointedly not continuing the conversation: telling someone to drop a subject would be rude in HC]
Japan is very HC. They call U. S. Americans rude for being direct, while our culture considers indirectness to be rude.
I learned that I was high-context after studying cultural differences for a semester in college. Fascinating subject, and very enlightening. I learned that there's really no such thing as rudeness, but there ARE people to be avoided for their embarassing or hard to deal with style of communication. Brentai is high-context and to a degree so is Sharkey. (you are not high-context at all, Thad) [did you see what i did there]
Man, that was difficult to explain! (please inform me whether I got the point across or not)
*in high context conversations smalltalk is replaced with a comfortable silence (in low context silence is mistaken for stupidity or agreement)
