Some people can use the Divide and Rule strategy so well! You wouldn’t even realize they are doing that! When you and a friend (or colleague or partner) are very close, and someone has a problem with your friend, and they come to you and complain about it. Beware! Get the reality first! Are they trying to divide and rule? Or are they genuinely interested in contributing to your friend through you?
It’s good to experience the strategy being applied on you! Just gives you a whole new perspective on people!
