But as the before-mentioned Peter Dinklage showed with his reaction to the calendar, we shouldn't take everything too seriously.

Psychotherapist and author Ilene S. Cohen, Ph.D., said that if you find yourself getting overly angry, upset, or defensive over little things, take comfort in knowing that there are actions you can take to more effectively manage your emotions.

First of all, know your triggers. "If we know what [sets us off], we can learn to be more in control of ourselves when our buttons are pushed," Cohen wrote. "Personally, I overreact and feel triggered whenever I work hard on something, and someone is critical of it. I’m pretty positive and encouraging toward others, and I can also take constructive criticism pretty well. However, if I think another person is being unfairly critical, it’s easy for me to lose it. Knowing this about myself, I become more aware of my reactions and try to more calmly respond to people when they’re offering criticism."

"Always keep in mind that if something has been bothering you for a really long time, the smallest inconvenience can push you overboard," Cohen explained.

"Try to address the past and resolve anything that’s truly bothering you in the present moment. If you don't, I can assure you that you’ll continue to sweat the small stuff. Address issues head-on as soon as they arise. Let it out so you can let it go and move on. Keep a journal, write a letter, do whatever it takes to talk it out. It’s no secret that life can get tough. And when things don’t go our way, it’s easy to lose patience. Try to manage yourself with the tips below, so that you can appropriately respond to the situations that arise in your life, one at a time."

Then, even people who are trying to get under our skin (including those who know what they're doing) aren't going to be a (huge) problem.
