The Quiet Girl in the Corner
You know the girl I'm talking about, the quiet one in the corner. She may not actually be "in the corner," but she's in the background, behind the scenes, never the center of attention, never in the spotlight. She's not friends with everybody, and she doesn't try to be. Instead she spends her time with a small group of close friends. You may look at her and wonder why she's not more outgoing, thinking it's not that hard to speak up.
But, don't be too quick to judge the quiet girl in the corner. She may be quiet, but she is not timid. Just because she prefers to stay in the background doesn't make her a wallflower, it just means she likes to observe what's going on around her. Staying out of the spotlight doesn't mean she's not fun-loving. The quiet girl still likes to go out and have a great time, but she's also the one who takes care of her friends when they have a little too much fun. She doesn't try to be friends with everybody because she believes in the value of a genuine friendship, but this does not mean she's not friendly and doesn't like meeting new people.
The quiet girl might be better with the written word than the spoken word. If you took some time to read her words, you might understand her better. Underneath her seemingly shy exterior may be a woman of great strength. You don't know what she has going on or what she's been through in her life. There may be a deeper reason for her quietness. The best way to find out what a quiet girl has to say is to ask her. Don't write her off without giving her a chance. She might end up being a pretty cool chick.
