I spent the day with a twelve year-old girl today. She watched as her brother and I played chess, and cheered me on as I was the foosball victor. :P As I read Calculus, I listened to her mother teach her the Biblical account of creation and later peeked in and watched her work on her lapbook. I listened to her practice the harp and reherse her finger-plucking, ready for her sister's lesson. All day she was smiley and jumpy and full of hugs.
I came home to another twelve year old girl. She has a boyfriend named John, but she's not sure if she likes him so she doesn't want to make a big deal about it in case they break up tomorrow. However, she asked her mother if she could borrow a "cute" shirt to wear to school in the morning. For her birthday, she wants an iPhone because her best friend has one, and a girl at school called her a [not-good-word-I'm-not-going-to-repeat].
I bet you the first twelve year-old has never even heard that word.
