Cheesy as it may be, more than a few times I've been truly moved by words on a poster or bumper sticker. For example: "Live so that when your children think of fairness, caring and integrity they think of you."
Spotting those words on a large poster behind a desk recently I felt compelled to engage the woman sitting there in a brief conversation. When was the last time words inspired you to initiate a conversation with a stranger? What were the words that moved you?
I had two thoughts prior to speaking to that woman. In the hopelessly naive vein - If she embodies the words on her poster even 20% of the time, she is making the world a better place. In the practical arena - I much prefer interacting with someone like her, however superficially, vs. someone who publicly displays a hateful or divisive sentiment on a poster or bumper sticker.
