4. Pepper Spray

A: My dad bought me a can of pepper spray.

B: Isn't that what police use on bad guys?

A: Yes, it's supposed to sting your eyes.

B: Why did he get you such a thing?

A: I feel safer walking at night with it.

B: Aren't you afraid you'll use it wrong?

A: No, it's pretty easy to spray.

B: What if it gets into your eyes and not the bad guys'?

A: Well, it's important to never spray against the wind.

B: Oh, I see. Then it won't spray into your face.

A: Exactly. It's a pretty handy tool.

B: I'd feel a lot safer carrying it, too.
