I saw a moonbow for the first time last night.

He went to Japan for the first time.

He ate sushi for the first time.

It was only after talking to him that I understood how smart he was.

Last night, I read an old book.

Last night, I read an old book.

Last night, he was reading an old book.

His behavior is really disgraceful.
