And That's How I Evaded My Breathalyzer Test

Had to pass through a sobriety check-point on the way home last night. You always hear about them, but I've never actually seen one in action. Four lanes of traffic funneled into one, then they stop 5 cars at a time. A very courteous cop & I had the following exchange.
Cop: Evening, Ma'am, County Police. We're conducting a sobriety checkpoint. Have you had anything to drink this evening?
Me: Not a drop.
Cop: Where you coming from?
Me: (name of town)
Cop: You're the 3rd person, what's going on up there?
Me: (laughing and a little sheepish) It feels a little odd to tell you this, but I'm coming from an hour of adoration of the Blessed Sacrament, making reparation for my sins and those of the whole world.
Cop: (laughing heartily) Ooooookay then (waves me through).
Well, he asked.
