There is no perfect person. The people who step into our lives and become acquaintances, friends, or significant others cannot be a complete source of light all the time, just as we cannot be perfect as well. People have flaws. And if those flaws happen to frustrate us, it’s actually an opportunity to learn a bit about ourselves.
Sometimes we’re irritated with others because their habits tend to remind us of our own habits we dislike, even if we’re not aware that this is the case. At other times, our irritation with others can come from our own preconceived notions of the world.
For example, you may come from a very clean household. If you move in with a new roommate who is messier, this can lead to irritation as you’re used to a different environment. Instead of holding a grudge, an honest conversation and negotiation can lead to settled, positive feelings.
Of course, sometimes our personality isn’t meant to mesh with other personalities. But even in this case, we can hold on to the understanding that everyone is different and learn a little about ourselves in the process.
