Difficult people

Yep, we all come across them from time to time - here are some ideas:

Do nothing, wait until they are receptive to your thinking.

Change your perception - ask yourself why are they saying/doing what they are doing. Dismiss the notion that they are bonkers and try to see it their way.

Change the context - what is it that has triggered their dis-ease? Try reframing the context and see if their behaviour now makes sense.

Motivate them to change their behaviour. State the obvious - if you carry on like this, then X (bad) will happen; if you approach the matter differently the Y (good) will happen.

Above all, concentrate on the difficult behaviour, not the person. Try and understand why their behaviour is 'difficult'.
