この間に、私の家族は田舎の自然に集めて、息子が従姉妹と一緒に小川に遊んだ
The other day my family

met in the countryside, and my son played with his cousins in a stream.

私も子供の時に兄弟と一緒にこんな遊びもよくした
I also had fun like this often with my siblings when I was a child

子供たちが遊んでる間私も色々な楽しい思いが出た
While the kids were playing I experienced lots of fun recollections.
