Conversation:

A: Listen, Jim. I've told you time and time again to keep the music down.

B: You know, I'm tired of you trying to tell me what to do. I'll listen to my music anyway and anytime I want.

A: If you don't turn the music down, I'll turn it down for you.

B: Are you threatening me now? Go ahead, make your move. 

A: Oh, you want to fight me? Is that it? You want to fight me?

B: I'll make you wish you had never been born.

2.be tired of...表示“对...感到厌倦；厌烦”；be sick and tired of...也是表示“对...感到厌倦”

3.turn...down表示“把声音调小”；turn...up表示“把...调大”

Translation:

听着，吉姆，我不止一次让你把音乐声调低了。

你知道吗？你老是告诉我该干什么，我烦透了。我想怎么听音乐，什么时候听音乐，我就听。

如果你不把音量调的，我就会替你调的。

你这是在威胁我吗？来啊，动手啊。

你是要跟我打架吗？是不是？你要跟我打架吗？

我会让你后悔来到这个世界上。
