Katherina's are very smart, loyal, creative, caring, and helpful. They are always trying to help other people and they try to keep our planet safe from global warming. Katherina's are mostly introverts, but they can become pretty extrovert when they want to. They'd rather prefer to stay alone and read a book than go out with friends and hang out, but they don't want to disappoint their friends, so they go anyway. They work very hard in their work, and they are kind of a perfectionist, but they can also be very lazy at times. Katherina's love to read and write their own stories, because they pour their emotions into their writing, as a way of relieving stress and frustration. Katherina's do tend to worry often, however, such as their future or their upcoming report cards or even how they look. Katherina's are also very smart, and they can often come up with a plan to overcome problems. But sometimes, they might be a little too smart for their own good, such as coming up with a plan to steal someone's wallet. And, they tend to get frustrated if they keep losing the same game, or if someone teases or makes fun of them. They will try and seek revenge, and they will always succeed, no matter what. They will always win an argument with you, so don't even bother. If you're close with a person named Katherina, then you are pretty lucky to have them. They'll always cheer you up when you're sad, and will never betray you for anyone else.
