there were times when
僕が子供の頃父は家にいなかった一度に何週間も留守にすることもあった
When I was a child, my father was often away from home, sometimes for weeks at a time.
— 甘い生活 (1960)
彼は勤勉だったけれども、ときには勉強したくないこともあった。
Although he was diligent, there were times when he didn’t want to study.
私は大声を出したのに、あなたは聞こえないこともあったわよね。
Even though I shouted loudly, there were times you couldn't hear me, right?
