Your son was an interesting kid, sometimes he was as quiet as a mouse but other times you couldn't move through the house without being told of his presence. It really just depended on the day. It wasn't that you minded Osamu Dazai's ramblings every so often, it was cute though sometimes inconvenient.

Dazai ran into the room you were currently in, holding a book you had bought him recently. He appeared very excited about something and immediately tried to talk your ear off no matter what you were doing.

He showed you a page of the book as he started to explain something about cicadas, completely ignoring the fact you were busy. He knew a lot about cicadas for some reason... Dazai always got very invested in his interests.
