Tell me about the experience of having a sister.

I'm glad to have a little sister, but on the other hand, I'm worried that I don't know how to take care of her. From how to teach her to walk and call people, to how to be her role model, I can't go wrong. So basically, I've been with her since she was born. As soon as she cried, I took her out for a walk and took the stairs. When she can't sleep, I play hide and seek with her. When she is tired of playing, she will drive her for a ride and let her fall asleep quickly.
