Breaking a Headlight

We are driving at night. An oncoming car has blue headlights.

Kid: Look at those lights!
Me: I think those are halogen.
Kid: What? Halo Legend?
Me: No, halogen.
Kid *laughs*: That is such a typical teen thing to mistake!
*pauses*
Kid: Why would they put drugs in there? Could you imagine if they broke? We’d all be stoned.
Me: What?
Kid: Oh, never mind. Those aren’t hallucinogens.
