Take, for example, the car below. Notice the super speedy pinstripes, without which the car would probably not even move. Two pink lines on a car? Awesome, 80s style. The stripes incite a feeling of zippiness that the car would clearly not have were it not for them.
Now let us take a look at a really good movie. Doesnt matter which one, pick any one you like. See those little pink lines, craftfully sealing that wondrous DVD shut, so that you know that some little punk has not previously watched it, burned it, and then brought it back to the store? Those two pink lines mean security people!
Now, see the below child. She's precious, isn't she? See that pretty little picture she drew? Its a rainbow, made with pink lines. Those pink lines represent unicorns and leprechauns and the innocent musings of a two year old, completely oblivious to the responsibility that comes with the other kind of pink lines.
There are times when two pink lines, that are relatively parallel to one another are completely harmless and benevolent. Take, for example, the picture of one of those annoying bicyclists riding down our country roads (in the most arrogant fashion BTW). See the stylish stripes on their shirt? Almost makes me feel bad for hating them taking up the road. Actually, no it doesnt.
