Understanding other people's personalities

A friend told me about this really cool website called www.personalitypage.com that shows you information about your own and other people's personalities. It's neat learning about other people and how they work, why they do or don't do the things they do. Reading my own personality type was so validating. There were things I found it very hard to express to others and explain about the way I am, and reading it clear in black and white vindicated to me why I am the way I am...Enjoy!
