Under the Crooked Neck Tree

I wish she has a beautiful sister who always pulls her timidity to try to understand the outside world. She always envied her sister's excellence and envied everyone's preference for her sister. But what she envied most was her sister's laughter, which was as endearing as the bird that always chirped outside her window in the morning. She has been mute since she was a child. If her sister is a light in his life, then she also has a light that she secretly hides. (I'm not good at writing, so I'll practice my writing skills) Concept: How can a mute speak of love?
