Thank you！ありがとう

Thank you for correcting the mistakes in my notebook.
Because I am an adult, it is difficult for me to learn English, but does I do my best.

I caused a minor collision by car yesterday.

While driving, I had a minor collision/accident yesterday.

I was felt bad because the other driver of the trouble was an old/elderly man.

I was bad.  僕は悪かった。

I felt bad.　不安を感じた。

I'm nervous... I must repair one's my own car and the car of the old man. 

事故の相手のことはなんというのでしょうか？.
Partnerではおかしいですよね。

"The other driver" を使ったら、明確な意味ですと思います。

大丈夫？怪我がありません？　気をつけてください！
