Chapter 1 observations and questions

So mine are:

* The narrators are probably boys, since the mention that they talk about baseball.
* Cecilia has traumatic experiences related to being a 13-year old girl, maybe because of the strict rules of her parents. She also looks like she never had a true childhood. when she is asked about the fish flies, she replies that they die in 24 hours, they only reproduce, the don't even eat.
* The narrators are used to the idea of the Lisbon daughters attempting suicide. many times they mention this very casually.
* Cecilia's mom is not to delicate with her after attempting suicide. When Cecilia asks her if she can leave the party, her mother responds "Fine, we'll have fun without you".
* Everyone in the neighborhood seems to be very interested in these girls, despite all the weird stuff going on in the Lisbon family.

My questions are:

* What could go so wrong that all the daughters want to commit suicide?
* What's so horrible about being a 13- year old girl according to Cecilia?
* Who are these narrators and why do they know so much about the Lisbon daughters?
