Summarize this article in one sentence.
There's a chance that a girl with her image and social history may be less open to making new friends. She could be hesitant to open up to you, or try to keep you from getting too close too soon. Don't be put off. Letting her know you like her and want the two of you to get to know each other is about being up front and, most importantly, being persistent. Don't be easily discouraged. No friendship falls into place right away. It may just be a matter of seeing her a few times and becoming more comfortable in one another's presence. Know when to back off. Though persistence is important, it shouldn't keep you blindly pursuing her if she's just not interested. Try to develop a sense of when enough is enough. If she feels like she's being harassed, it may make her even more closed off. No matter what your intentions are in getting to know her, the strongest foundation is friendship. The two of you will most likely start off as friends, and you may even find that this is more meaningful to you than dating her would be. Don't try to force her into anything or expect things to move too fast. It's up to her whether she wants the relationship to progress; in the meantime, let your friendship be its own reward. Others may be reluctant to become friends with her based on the way she looks or acts outwardly. Try to see past the "tough girl" label and get at the essence of the person inside. We're not all that different at the end of the day. Become a reliable figure in her life. Always be ready with a helping hand and prove to her that you can be trusted. She can be the most capable person in the world, but it will still mean something to her to know that you care. Make yourself available when she needs you. Be someone that she can talk to. That means being honest and straightforward with her, withholding judgment and making her feel at ease. No matter how tough or independent she is, no one minds receiving a compliment. Pay attention to more than just her physical features. Single out the best parts of her character and give them the praise they deserve. Sometimes she might just need to hear that someone else likes the same things about her that she likes about herself. Encourage her individuality, don't make her feel self-conscious about it. Attempts to change her subtly by saying things like "you shouldn't be such a loner" or "see, you look good when you get dressed up" will only be met with resentment. Lavishing her with too much praise can become tiresome. Say something nice about her when it's warranted; otherwise, it's best not to be too heavy-handed with affection. Make her feel appreciated. This is a much more significant thing than just telling her she's pretty or complimenting her hairstyle. True appreciation stems from recognition of someone's positive qualities and successes, and these are the things you want to celebrate with her.

Summary:
Don't let yourself be chased off. Be a good friend. Let her know she can count on you. Tell her what you like about her.
