Dear Ann,

While I was reading 'Sugar, I came across your

I decided to write to you because we seem to have a lot in common. At least we both like reading the same magazine. I'm 15 years old and I live with my brother and parents in Sydney. You could say that I live with my parents but I don't see them very often.

My Mum works for an advertising agency. I think her job is much more interesting than my Dad's. I get on very well with her, but sometimes she worries too much.

My father is a bit of a workaholic. He works for a big publishing company. He works late hours, even weekends. He's nice, but when I go out, he wants me to be back by 10 o'clock

I like drawing a lot, I'd like to be a designer or maybe

illustrate children's books. I've taken up extra painting.

classes and it's a lot of fun. My brother thinks I'm not

talented at all but that's my brother. He's a bit of a

weirdo, anyway. He is 18, but still spends most of the

time on his skateboard. He has a bunch of friends who are

all crazy about it. They all think they are cool.
He hopes to become a famous musician. He spends hours

practising, the rest of the time he teases me. He's taking

exams at the moment. He pretends to be studying, but he

is playing computer games or watching videos. My best mate is called Eve. She's a real friend. She never lets me down. We go to the same school. When school is over, we go to the beach to watch windsurfers. I like one of the boys there a lot. Eve says he is a real joker. His name is Pete, but he doesn't even notice me.

This weekend I'm going birdwatching with my parents. We will до into the bush with binoculars, sleep in tents and have a lot of fun. Eve's coming with us and we have to catch up with all the news. That's all for now! I hope to hear from you soon.
