Reirei's been thinking quite deeply lately, once after Sakurako's post and now Tagucchi 's.
In my attempt to summarise both posts together (corrections are welcome) - Her mother always wanted Rei to become a person who is considerate of other people's feelings. Even if misunderstandings occur between both parties, it can become a learning experience and important for self-growth. People have their good sides and bad sides but it'd be good if we could connect with their good sides as encounters are always followed by departures (especially with people like Harunan, who has lots of goods points, she says ). She wants to try and cherish her encounters with people she has met even after they go and look forward. Also doing things like talking it out with her mother and writing her stuff down on a little piece of paper or notebook and not reading it back again in order to move on when she's feeling troubled.
Despite being the youngest in the group, seems like someone who has a lot of empathy, particularly towards the other members; showing more emotional maturity than myself
Also she is very into Aida Mitsuo's poems lately. I have very little knowledge of his poems though but the gist I get from them is "what you do right now is most important".
