A very challenging person could test your patience to the breaking point today, but you can handle things just fine if you don't take their behavior personally. Remember that they are like this with everyone, not just with you. Focus on what benefit they bring to your life, and if you can't come up with anything, then just get your distance from them for a while. Understanding why you need to tolerate their behavior will help you get through it. Luckily, their presence in your day will be brief.
