My older sister complains that she did too much housework, child caring when she was young. She is the oldest one, and 7 years old than me. I am the middle child, and my brother is just 2 years younger than me.
We do have totally different character: my sister is the most successful one, reached really high almost all by herself without parents' help. I am an easy going one with an easy life. My brother is the spoiled one who is still depending on our parents, but they feel happy to support him.
