My birthday is on XXX. I always have both happy and sad feelings on my birthday.

Why I am happy? I have group of friends that come over to celebrate with me. And they give me birthday presents， sometimes the gifts surprised me very much. Also， I can feel how much my family loves me because my parents always make a birthday cake for me.

They do not go to buy one， but make one themselves. I feel so happy about that. However， I understand my mother was the one who suffered the most pain on the date I came to the world. I feel so sorry for my mother for what she had suffered. But I promise her， I will take good care of her when I have that ability.
