No two people will agree on something 100% of the time. It doesn’t matter what it might be people will have different ideas about how to go about doing something. We live in a world of human beings who have different experiences and that informs who they are and what they think. Working with people from different backgrounds can challenge and frustrate.
It gets bad when you have different agendas. When you care about the same things very deeply and you have different ways of supporting it is when you find that your patience can be challenged. To keep the peace you have to agree to disagree and find common ground in other places. Relationships can test you this way.
The temptation is to walk away but perhaps working through the differences can be an opportunity for growth. So many people will walk away from something they love because of their experiences with someone else. Remember you have every right to be there too. Hang on in situations like that.
