The best lesson my parents have ever taught me.

There are four people in my family, my father, my mother, my younger brother and I. We live happily. My parents are typical traditional virtuous parents and good parents. What is the best lesson my parents have ever taught me? I think it is love. My parents love each other deeply though they have married for nearly twenty years, and they love us deeply too. Years ago, dad set up a company and he is very busy in business. In order to take good care of us Moms resigned from the work and spends much time on us. Thanks, my dear parents, I love them from the bottom of my heart. I know the best way to thank them is to study harder and don't let them down. I love my parents.
