When I was ten years old, I wrote a letter to my mother in 50 words.

Mom, I am ten years old today. Thank you for giving me life, taking care of me and making me the happiest child. When I grow up at the age of ten, I can also protect and take care of you. I've been thinking about mom, when you get old, should I take care of you in every way? You will be a child then, just as you took care of me.
