うごいてみのむしだつたよit moved — so it was a bagworm

枯葉か木くずかと思っていたものが、ふいに動いた。なんだ、蓑虫だったよ。「だつたよ」という話し言葉の結びが、そばに誰かいるかのよう。一人の旅の発見は、つい誰かに報告したくなる。What he took for a dead leaf or a wood chip suddenly moved. Well now — it was a bagworm. The colloquial ending "it was, you see" makes it feel as if someone were beside him. A discovery on a solitary journey makes you want to report it to someone after all.
