Always attempt to be clear in perception.
The Buddha might warn us that the majority of people are having misperceptions at all time. Christ hints at similar things though uses different language.
We bring to the table so many biases, so many clouded judgments, so many perceptions that don't necessarily reflect reality that we're more than capable of reading terrible things into a situation that's otherwise benign.
You can be certain of how you feel and what you're thinking, of course; what's less certain is why you're feeling and thinking those things.
What's even less certain is how others feel and think, and the why thereof is almost inscrutable entirely.
Bear that in mind when there are disagreements of opinion and even downright conflicts.
The last thing any of us want to do is to create more strife in this world. At least most of us who are mystics are more inclined to try to create harmony and peace.
Perhaps some people think that harmony and peace are boring, and I can understand why people might think it's boring; if there isn't some kind of story arc, if there isn't some kind of beginning, middle, and end, if there isn't a hurdle to overcome, then where lies the meaning?
But that also demonstrates people who haven't actually experienced harmony and peace for themselves! On the contrary, meaning is very apparent when one is peaceful. When one experiences flashes of unity with God, reality presents itself much, much differently, and the normal strife disappears.
Indeed, as a matter of personal experience, I can testify that experiencing harmony and peace is anything but boring. In fact, that dynamism of reality is so mighty that it's almost difficult to keep up with, and that's likely why we fall out of those states.
Back to the original point: don't mistake another person's grumpy mood for being something that you personally did. Oftentimes, that's not the case, if it's ever the case.
For those who watched Bishop Tom and Brian's wedding ceremony, I would recommend practicing the rose ritual with your significant other. The rose ritual is an incredible way to remind us what's important in life and to clear our misperceptions.
