Only two people, I have some idea but I'm not 100% sure on them...
She is very intelligent and capable, and is a little shy in public. She loves to plan family/close friend events (loves to plan what food to eat, what games to play, etc.), even though sometimes those plans don't always go through. Still loves planning those type of events despite that. Has once stated that she hates people in general, but she could have been having a bad day then. Can get angry or upset easily if people tell her something she doesn't want to hear and she can be sensitive. Doesn't express much empathy. Has sudden passions and interests (she can somehow one day get interested in something that she wasn't previously interested in).
Not the most patient person in the world. Can hold grudges for a significantly long time. Not the best listener in the world, sometimes she and I clash over being heard. Can be a very hard worker at times, sometimes skipping meals to work. Is very careful with money she spends, and can at times seem a little greedy.
He is extremely intelligent, and very very laid back. Loves to have a good time, although he will get work done that needs to be done. Seems to always succeed, even without putting in maximum work effort. Has said before that he likes to hang out with his friends, but not with people that he doesn't know. A very courteous person, good guy, good friend. Can't stand a few certain people but will not show his displeasure. Doesn't really show it when he's angry or sad. Seems happy a lot of the time. A great listener. In crowds, he's generally more quiet unless there are extreme introverts in the crowd. Does things quick and efficiently, makes things look easy. Can be very creative.
Is passionate about heavy metal music. Usually is active, and encourages friends to do fun activities with him. Although he competes in athletic feats (for fun, not on a team), he cares more about having a good time than winning. He is very confident in his abilities, but NOT cocky at all, has a quiet confidence about him. Has a lot of trouble keeping with timings, and sometimes I get angry at him for this. Often quite forgetful, but he never worries (at least it doesn't seem like he does). Comfortable talking to a group of people, good conversationalist.
Thanks a lot, I appreciate it.
