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.
