答案解析：
B
整个对话内容：男士不小心闯进女士的浴室（或者别的房间，反正女士是裸着身体的），于是女士开始对男士进行指责，而男士说女士衣服还没穿好，依旧能看到她的某个地方（你懂得）。 因此，A 不正确，因为这和 family 无关；B 正确；C 不正确，没有碰撞；D 不正确，one thing 是指后面的善意提醒。

听力原文：

Rachel: That is IT! You just barge in here, you don't knock
Chandler: I'm sorry!
Rachel: You have no respect for anybody's privacy!
Chandler: Rachel, wait, wait.
Rachel: No, you wait! This is ridiculous!
Chandler: Can I just say one thing?
Rachel: What? What?!
Chandler: That's a relatively open weave and I can still see your... nipular areas.
Rachel: Oh!!
(She storms off)

听力笔记：

That is it: 够了，好了，注意此时Rachel的语气，表达愤怒。
Barge in:闯入，干预。【例句】Don't barge in on our conversation. 在我们交谈时别嘴。
