I stole this quiz from a friend of mine, and although I'm an only child, it pretty much pegged me here (although what if I really am a first born, and there's some dead scary brother/sister out there that is going to haunt me like in the scary movies? :)
You Are Likely a First Born
At your darkest moments, you feel guilty.
At work and school, you do best when you're researching.
When you love someone, you tend to agree with them often.
In friendship, you are considerate and compromising.
Your ideal careers are: business, research, counseling, promotion, and speaking.
You will leave your mark on the world with discoveries, new information, and teaching people to dream.
