You Have the Most Leverage
We can hope that people we find difficult will realize how unreasonable they are and will change on their own, but they won't. They won't wake up and change because they don't see themselves as difficult or inappropriate. These troublesome (to us) people believe they are acting in a reasonable way. In fact, they may wonder why other people are so upset.
When you feel yourself becoming upset, ask yourself if you've been clear in what you expected from the other person. Check on your emotional response. If you are having a strong response and wondering why the other person doesn't get it, it may be a clue that someone just walked all over your boundary lines for acceptable behavior.
Understanding why people drive us to distraction at work doesn't mean you have to tolerate behavior that you find distressing. Talia could set a boundary with Frank by saying something like "Frank, it's fine for you to use my computer as long as you return the settings to my preferences when you're done."
You can always make a request for a change-not for the other person to fix herself, but to respect your boundaries or find a third way that will work for both of you.
Life is too short to let the people we work with fray our nerves. We can't change those irritating people, but we can recognize the source of our irritation and change our own response.
