I Can Do Little or Nothing

Today, I tried to go to my university.

However, I couldn't enter the building because the card key wasn't found.

Perhaps, I left it with my wallet behind in my laboratory.

I contacted the laboratory's members, but everyone was taking a vacation.

I wanted to research at my university, but I am studying English at my apartment now.

私は今日、学校に行こうとしました。

しかし、カードキーが無かったので入れませんでした。

恐らく、財布と一緒に研究室の中に置き忘れたのだと思います。

研究室のメンバに問い合わせましたが、誰も居ませんでした。

大学で研究をしたかったのですが、今は家で英語の勉強をしています。
