-Wallflower

"Someone who isn't necessarily shy, but never really tells you a lot about themselves. They observe almost everything and listen to everything you have to say without criticizing or judging. These people are often the most sincere, kind, and wonderfully interesting people, yet fail to be attractive to the opposite sex for some reason. A person nobody pays attention to, and fades into the background, but are really genuine and interesting people if you take the time to get to know them."

I am a wallflower.
