The most important thing in my life is my family. We are very friendly and
always together. We know how to support each other and do this all the time.
My parents are great people and they taught me many important things. I love and
respect all my friends and relatives. I remember all good things they have done for
me and I want to help them as well.
Family is the thing that can make us happy and upset few times per day. We can
argue, but at the end of the day I understand they are the best people in my life.
Children have to help the parents. Yes sometimes we want to have fun or go to the
party, but first we have to help the family. I know that my mom and dad work hard
to grow us up and give us better future. So I am really thankful and I would like to
make their life easier. I wash the dishes, clean my home, help to cook and help
with shopping whenever I can. Family values are very important nowadays. But I
hope that in future everything will change and family values will become popular
and important for every person.
