This translates to “Why is Chapter 3 called "Nobody's Letters"?. I’m pretty sure you’d just have to read the text and figure out why the author chose to name it this.
Umm te refieres alguna música o algo?
Canciones de eso?
It would be;
Antes mi hermanita le TENIA miedo a los perros.
TENIA is the past form.
Hope this helps (not sure if this is what you needed)
