Am I an Introvert or Extrovert?

For the most part, I am an introvert.  However, for some time, I have thought that I do have occasional times when I feel like an extrovert.

Most of the time, I usually prefer staying at home and working on personal projects like writing stories and drawing - and also think about many philosophical things.  I get so caught up in my hobbies - but also procrastinate and tend to lose track of the time, so minutes become hours, hours become days, days become weeks, weeks become months, and months become years.  Something that I plan to do "within the next day or two" often ends up being several weeks, months, or even years later.

I also hate talking on the phone - even with friends and family, so I could say, "Yeah, I'll call you back later" - but then lose track of the time and/or procrastinate - and never do get around to calling anyone back.  They're usually the ones that end up calling me.  It's a combination of both losing track of the time - and also just hating talking on the phone in general.

I hate talking on the phone, but I also tend to shy away from other forms of conversation.  I hate having to commit to a conversation - and like being able to do things that I want on my timetable, so it could also be a bit of laziness, too.  But yeah, although I hate talking on the phone worst of all, I also shy away from chatting on Facebook and even hanging out in person.  After a few minutes of talking on the phone or chatting on Facebook - or after a few hours of hanging out, I usually feel the strong urge to want to go back to my own, secluded life.  It's nothing personal against anyone that I talk to or hang out with, though.

Within the last few years, I found an article called "Don't Call Us, We’ll Call … Well, No, Actually We Won’t..." by Sophia Dembling on February 22, 2010, on Psychology Today.  I have a lot in common with what was described in that article, and its title sums up how I am.  I pretty much never call anyone voluntarily - they're always the ones to call me.  I also really hate how loud phones can be.  Also, when I first found the article, I was shocked to see that the article listed Tetris and FreeCell as games for introverts to play because both of those are my favorite computer games!  I guess many introverts think alike.

The strange thing, though, is that despite being largely an introvert, I do feel rather extroverted at times.  There are sometimes when I absolutely love socializing with people, but those times aren't particularly common, and they can't be forced on me.  Basically, although I can be extroverted at times, it has to be when I'm ready for it - and when I want to be extroverted.
