I took this and got 'Diplomat'. However, what I would have done in those situations wasn't always a given option.
Here, instead, is what I would have REALLY done if any of those situations had come up:
You overhear your boss complaining about your job performance. You:
Double down and make the best numbers you possibly can, just to show your boss you're not worthless.
Your roommate keeps eating your food, even though you've asked her to stop multiple times. You:
Take all of your food that doesn't need to be refrigerated, and hide it in your room. You lock your door when you're out of it, too.
Your sweetie is getting mysterious late night text messages. You:
Feel happy for them, that they've found someone interesting to talk to. You monitor the situation from a distance for a few weeks, to see if your S.O is still talking to this person all the time, and if they are you might feel a little regret that maybe they're growing away from you, and you wish that they would tell you if they're secretly seeing someone else (since you're fine with that), but on the whole it doesn't matter. Let them be happy.
You have a horrible server at your favorite restaurant. You:
Silently deal with the horrible service, and wonder if something's going on that's beyond the server's control, to make the service so bad. You feel a little disappointed, but not at anyone in particular, just the situation. You leave an average tip, or maybe even a little extra, if you see that the server's having to work extra hard that day.
Someone cuts in line in front of you at the grocery store. You:
Say "Hi, sorry, uh..." and then point at yourself. People usually get the idea.
