”這是他家的事”這段對話可以幫我翻成英文嗎

Armor: I really master him to think any, unexpectedly makes this kind
of matter

Second grade: How do you manage him to think that, this is his
family's matter, he likes making any to go along with him.

不知是否對
對的話***名子到部落格長期留言還要找人去

A:I really understand what he is thinking , unexpectedly do such a thing.
B:

甲: 我真的搞不懂他在想什麼,竟然做出這種事情來.
- I really have no idea why he did that. What the hell is he thinking about?
- I don't have any idea why he did that. What on earth is he thinking about?
- I really don't have a clue why he did that. What is he thinking about?
- I really don't know what he is thinking about and why he did that.
- I really don't know what's wrong with him and why he did that.
- I really don't know what's wrong with him and why he did such a thing.
- I really don't know what's on his mind and why he...
- I really don't get it why he did that. What is he thinking about.

以上是一般對話可能聽到的表達方式 (expressions) 前面的主要子句可以依自己喜好選擇 可以分兩句講 也可以用一個句子
以後有類似狀況 自己可決定要怎麼表達

* the hell: (口語)語助詞: 到底
* on earth: 到底
* have no idea = not have a clue = 完全不知道

乙: 你管他怎麼想, 這是他家的事,他愛做什麼就隨他去吧.
- Never mind. That's his own business. He could do whatever he wants.
- Forget about it. That's...
- No need to think about it....
-... He has the free will to do whatever he wants.
-... Let him do what he wants.
- Don't bother worrying about him...

以上 expressions 也是隨意組合 只要達到你想說的就好

學英語最最重要的是: "不要翻譯!!!" 要問: 這句英語可以怎麼說? 應該怎麼說?
這樣才有可能 "用英語思考" 而且比較不會說一口洋涇濱英語或台式英語 聽得老外滿頭問號 不知所云

歡迎指正

A: I don't understand what's on his mind to do that.
