Sorry, My Brother / 弟よ、ごめん

今月入籍した弟は、実家の敷地内にある家で奥さんと暮らし始めました。

My brother got married this month. And he began to live with his wife at a house on the premises of our parents house.

父母の住む家と弟夫婦が暮らす家は、水道代の請求が一緒なのだそうです。

実家の水道代はこれまでほぼ一定だったので、今月分からは増えた分の差額を弟夫婦にキッチリ請求する！ という取り決めになったとのこと。

Payments for water bills are not divided between the two houses, and parents are charged water fees of both of them. My parents' water bill was nearly constant until last month, so it became a rule to charge my brother for just increased amount from this month, my mother said. Well, it is irrelevant to me. I thought so, but ...

私は「ふーん、そうなんだ～(他人事)」という感じで聞いていたのですが、

帰省するなり、退屈のあまりホースで水遊びを始めた長男。

As soon as I arrived at my parents house, my elder son started playing with water because he was bored.

弟よ、ごめん。

Brother, sorry.
