[QUOTEDoes body language count in this?
Does anyone remember the shift in the services from pointing an index finger and saying "Oi, you!", to the flat palm, 4 finger point?][/QUOTE]
Don't point - indicate!
Pointing at someone is rude.
Imagine scenario, briefing room, main man is all serious about this and that, and someone lets rip.
Now should he turn around and point at who he considers the culprit, and suggest he speak clearer if he has something to say, would be downright rude, and may lead to a false allegation and all the consequences involved. Ends up nasty.
All the better to turn around and indicate the general direction of the noise and inform the group that the noise maker may want to consider going for a crap as breaking wind is natures way of saying its time to drop the kids off at the pool.
