Since I am first of all a character writer, that character's emotions are as vivid to me as my own. I always begin with an emotion after I have established a character in my mind. I feel what they feel. I guess that is why it comes across so strongly.
I do feel that the boys are getting left out. Girls will read boys' books, but boys won't read girls' books. If you're writing for a girl, you've got most of the audience on your side anyway.
I grew up with my cousins, who were as close as brothers, and frankly, I didn't like what girls were expected to do. I liked horseback riding, playing football, going to rodeos. I wanted to be in jeans all the time, and I couldn't figure out why I was supposed to conform to a certain standard, so I didn't.
'The Outsiders' cast in particular was a joy to be around - sweet kids, normal goofy teenagers off camera and serious artists on. They were great. I never got them mixed up with the characters, though. Each of them had his own strong personality.
How a piece ends is very important to me. It's the last chance to leave an impression with the reader, the last shot at 'nailing' it. I love to write ending lines; usually, I know them first and write toward them, but if I knew how they came to me, I wouldn't tell.
I was a 'young adult' when I wrote 'The Outsiders,' although it was not a genre at the time. It's an interesting time of life to write about, when your ideals get slammed up against reality, and you must compromise.
