“Okay, see. This year (7th grade) I found out that I needed glasses to see better. I almost freaked because most people get their glasses before they reach the teen age and they all had contacts and stuff. So I got really vain and I never wore them. I would squint to see the board or move up.I´m afraid that if I wear my glasses everyone will think I´m a dork and no one would like me or something. What should I do? I am so vain and I wish I could be like those witty little girls who are so joyful all the time.”
