You are very organized, more abstract, and both introverted and extroverted.
Here is why are you Big Bird.
You are both very organized. You almost always know where your belongings are and you prefer things neat. You may even enjoy cleaning and find it therapeutic. Big Bird is never sloppy and always under control... pretty good for a 6 year old bird living without a family.
You both are abstract thinkers. Big Bird is a dreamer who always wonders what the world is like. You definitely are not afraid to take chances in life. You only live once. You may notice others around you playing it safe, but you are more concerned with not compromising your desires, and getting everything you can out of life. This is a very romantic approach to life, but hopefully you are also grounded enough to get by.
You are both somewhat extroverted. Like Big Bird, you probably like to have some time to yourself, but you do appreciate spending time with your friends, and you aren't scared of social situations. Big Bird is always very comfortable around others, but he often prefers the quiet low-key presence that Snuffleupagus provides.
