| ||Body language|
Body language is problematically ambiguous to a degree that, at times, it can make a staple-gun seem like a rocket launcher.
The same gesture may have many different interpretations, some of which will be detrimental to a teacher’s image. Consider for instance the simple body language gesture of scratching the nose. This could have many different interpretations, ranging from lying to having bad hygiene to, of course, just having an itch.
