两句中文翻译成英文

Loneliness is a person's Carnival, Carnival is a lonely person

Loneliness is a human carnival, carnival is a lonely people.

我知道一句原话叫 孤单时一个人的狂欢, 狂欢是一群人的孤单.
跟你的有点出入. 这句话是 ：Loneliness is a human carnival， carnival is a group of lonely people.

Loneliness is carnival(狂欢) for the one. Carnival is loneliness of the many.

Loneliness is a person's carnival, carnival is a person's loneliness.
