The older I grow,the more thankful to parents I am
When I was a little kid,I always depended on my parents.But when I became a junior
middle school student,I wanted to do whatever I wanted to do.When my parents didn’t allow me
to do so,I was always angry with them.And they felt very sad and disappointed.
As I grow older,I feel I should do something to make them happy.What should I do?
Firstly,I’ll help our parents to do some housework.For example,I can wash dishes,clean
the floor or wash the clothes.I think doing these things will make them feel warm.When
they get ill,I’ll take good care of them.
Secondly,we should follow their instructions.When they tell me to do something,
I'll try my best to do it well.I’ll study hard and get good marks.I think they we’ll
be happy to see that.If I meet with some difficulty,I’ll turn them for advice.
Thirdly,I’ll be polite to them.I won’t argue with them.I’ll try to make them happy.
My parents give me life and love.I’ll give them love in return.
So the older I grow,the more thankful to parents I am.
