So:
-Introverted, likely enjoys being alone rather than hanging out with other people.
--Not very energetic in the company of others.
--Doesn't talk much, if she does, probably short and to the point?
--Misanthropic
--Thin-skinned and quick to anger?
-Takes small things way too seriously
--Spends a lot of time on the Internet
--Argues a lot on the Internet
--Internet easier to deal with than actually engaging with others
-Generally not a happy person?
-Likes animals

--They're soothing to be around?
