毛拉和哈皮讨论的是，英语中有很多与地点有关的英文表达。

Harp: Let’s look at some space-related idioms.

Maura: So, the first one is Are you from Mars?

Harp: No, I’m not from Mars. I’m from Earth.

Maura: So, you might get asked if you’re from Mars, or ask someone if they’re from Mars, if they’re very strange and bizarre, doing things differently than how most people do.

Harp: Yeah. I think kids use this expression the most.

Maura: Yeah. But again, with this, you wanna make sure you ask a friend or someone you know. You don’t say this to someone you don’t know very well, because it could be rude then.

Harp: Yeah, and don’t ask your boss.
