While taking their usual bath, the boys discuss how much Kyotaro is like an old man. The next day, when they go to school, they find themselves exhausted by climbing up the stairs... and learn that they're all becoming old men!
Either way, it's a little 
too soon for us to be old.
على أي حال، ما زال من المبكّر كثيراً
على شيخوختنا
Wie dem auch sei,
es ist noch zu früh für uns, alt zu sein.
Como sea,
es pronto para envejecer tanto.
En fin, es pronto
para envejecer tanto.
En tout cas,
il est encore trop tôt pour vieillir.
In ogni caso, è un po' presto per noi
per invecchiare così.
De qualquer forma, é ainda
muito cedo para sermos velhos.
Как бы то ни было, рано нам ещё стареть.
