今日は良い天気だったので、午後に息子と一緒に公園に行った
Today was good weather, so I went

to the park with my son

誰も居なかったので、息子は一人でちょっと遊んだ
Nobody was there, so my son played alone a little

でも確かに子供が子供と一緒に遊びたいので、息子が早くてつまらなそうになちゃった
But of course children want to play with children, so my son seemed to become bored quickly

私なら木の下の影で本が読みたかったのに
As for me, I wanted to read a book under a tree in the shade
