You just brought back an old memory. I was driving home from college for vacation. It was about 1969 so you can imagine what I looked like. A statie pulled me over.
"You didn't signal when you changed lanes back there."
"That's impossible. I always signal." (I still do, even at 3 am with no one around.)
"Hmph. Any drugs in the car, kid?"
"No."
"Mind if I look around?"
"Be my guest."
So he glances at the interior, takes a sniff or two, then asks me to open the trunk which, of course, is filled with all sorts of junk plus a big suitcase (gotta bring home the laundry, right?) I open the trunk, stand in front of him with the universal facial expression meaning, "So help me, if you ask me to open the suitcase and start rummaging through it, I'm gonna say something I will regret when I regain consciousness."
He looks at me for a few seconds. Then.
"Okay, kid. Hmmmm. Maybe you did signal back there."
