Mom is the best for me. Whenever I was sick or had a high fever, my mother was always the one staying up late, devoted to taking care of me. When I did something wrong, she didn't blame me or hit me, but she just told me to learn from it for the next time, I'm really very grateful and proud of her. Although my mother often has to come home late due to work, whenever she has free time, she always spends time playing with me. I want to tell the world that 'there's nothing better than having a mom around'. I love my mom very much.
