Yoko is startled. It is that the apartment where oneself live in gained the name of the bird every ridge. hato〔鳩〕,tubame〔燕〕,ohotori〔鳳〕, thidori〔千鳥〕......etc. In this apartment, the all the ridges were comprised of the name of the bird. Though the inclination that affected the success or failure of things too much included it, mother regained an extremely normal sense when she stood opposite to a small bird. Yoko gets a hint.
