Twilight stared blankly out the window of Sunset's apartment in the human world. Below her passed a firetruck.
Wait... Twilight thought, If a firetruck puts out fires...
Does a water truck set things on fire?
If a garbage truck takes away the garbage, does a sanitation truck make everything dirty again?
Does a milk truck deliver milk or cow juice?
What kind of paper is the paperboy really handing out?
When you clean a vacuum cleaner, do you become a vacuum cleaner?
Twilight's train of thought was derailed as she saw a giant Thomas the Tank Engine transformer thing running down the road, chasing the firetruck that had passed moments earlier.
