My sister and I are very different. When people meet us both, they are always surprised to learn that we are sisters. This is because we don’t look like each other, and we have different personalities(性格).
Are you similar to your brother or sister? My sister and I aren’t  similar to each other at all. I am tall, but she is very short. I have short dark brown hair and green eyes. She has long blond hair and blue eyes. I am strong, but she is not. I have big hands and feet; her feet and hands are very small. When we are kids, she was thin, but I was heavy. Now we’re both heavy.
We also have opposite personalities. She is always shy. I am more outgoing. She is very worried about what other people think and say about her, but I really don’t care. When she has a problem, she just worries about it, but when I have a problem, I try to fix it. She easily gets angry, especially with our mother. But I am more patient.
