A very demanding person could test your patience today, but you can pass the test with flying colors if you maintain a good attitude. First, don't take their behavior personally. They are like this with everyone, not just you! Second, focus on what benefit they bring to your life. Understanding why you need to tolerate their behavior will help you get through it. Luckily, their presence in your day will be blissfully brief. You'll just have to grin and bear it.
