必要は整理整頓の母ですね。 Necessity is the mother of tidying up, isn't it?

　停電がありました。

懐中電灯はベッドの横に置いてあります。

ライターと蝋燭は棚の横が定位置です。

すぐ蝋燭を灯すことができます。

皆さんの住環境と違って停電が多いのでいつの間にか置き場所が決まりました

必要は整理整頓の母ですね。

 There was a power outage.
The flashlight is kept next to the bed.
The lighters and candles have their designated place next to the shelf.
I can light a candle immediately.
Unlike where you all live, power outages are frequent here.
So I've unconsciously chosen these places for them.

Necessity is the mother of tidying up, isn't it?
