There is a difference between being difficult unnecessarily because we know we can and know we’ll get away with it and being difficult unnecessarily because we struggle and fail to cope.
We may still choose to let their behaviour to go for a quiet life, so as not to rock the boat and because in the short term it may seem easier, but in the long term it’s something that never goes away. If we continually have someone in our lives that mirror that behaviour, then perhaps it’s time for us to let them go.
It’s generally accepted that if we’re struggling with something and being difficult and it’s a one-off, then that’s okay, but being difficult for difficult sake, is never a good thing.
Of course, dealing with any conflict takes energy, patience, maturity and experience. It is important in those situations, we stand back so that we can work on being objective, calm and dispassionate.
You could always choose not to have unnecessarily difficult people in your life.
