All three of the trio seem to have something less than normal home lives. Death, divorce, guardians ... How do you think that this has made them the unusual "little girls" that we see in Kodomo no Jikan ?
What would change about their lives, if you could, to make them happier and maybe more normal?
Have fun with this topic.

I think it's very clear that Rin shouldn't be living where at that house any more in light of the episode at the end of the first season with the scisors and attack by her guardian.
