My parents always expresses love to us and take care of me.
So I think parents have the right to expect their children to take care of them when they grow old.

First, Parents take care of their children throughout their childhood and school years.
They provide food, clothes, and education. They try to help their children when they have problems.
And it means that children owe to their parents about wealth and health. So the children should make it up to their parents.

Second, taking care of parents is a way to show love and gratitude toward their parents. Parents may become weaker and need help from their children. At that time, children can help them with housework, take them to the hospital, or spend time with them. These act can make parents feel loved and less lonely.

In conclusion, I consider that parents have the right to expect their children to take care of them when they grow old. Therefore, they will feel love and confort to their loving dauthers and sons.
