Deer caught in the headlights

Driving up Wilshire on our way back from LACMA, we see an elderly couple driving a bmw next to us. They're nicely dressed, as if they're on their way back from some evening gala somewhere in Beverly Hills. Nothing wrong, of course.

That is, until the old lady in the passenger seat holds up a bong. We're stopped at a stoplight, staring at her intently; just as she's about to light it, she looks up at us with the most horrific look on her face. You know, that exact same face a teenager has when his parents walk in on some illicit activity (Of all the things kids do..hell, take your pick). As luck would have it, the light turns green at that moment, and her husband speeds off. I have never (no not ever) seen an old man drive a bmw so quickly.

Mind you, this is an old couple in their late 60's. Granted, she may have been smoking something else. Cloves, maybe. But why else would she have that look of utter terror? I'll probably have the image of that old lady's face ingrained in my mind for a while. So old people do smoke pot. =D
