My Dearest Friend

1. Sunny and I met on the first day of secondary school on a warm autumn day. After class I told her that her name described the weather perfectly that day. She laughed, and we became friends.
2. Sunny is an attractive girl in her late teens. She is tall, slender and dark-skinned and she usually wears her shoulder-length brown hair in a ponytail, which highlights her high cheekbones and long oval face. When she smiles, her almond-shaped eyes sparkle and her whole face lights up. She wears light makeup and fashionable clothes.
3. Sunny has an incredibly warm personality. She is supportive and knows how to encourage people when they’re feeling down. However, she tends to be very stubborn and determined. Once she’s made up her mind about something, no one can make her change it!
4. Sunny always lives life to the full. In fact, she finds it very difficult to sit still for long! She’s always humming her favourite songs, too, whatever she’s doing! She’s adventurous and loves discovering things about people and places.
5. Sunny is a marvellous friend who really lives up to her name. I find it hard to imagine what my life would be like if I hadn’t met her.
