The Art of Selling Lemons

Imagine if you will, that Earth is visited by handful of aliens. Their powers are awesome, and they are telepathic. So awesome, in fact, that they really aren't interested in competing with us, as much as we try to provoke them.
One of the aliens befriends a young disabled French boy. On their first visit they tell us about how they, as outsiders see us humans, which often contrasts with how we see ourselves. They point out the contradictions in what we say ... Something I call ‘Lemons'... Twenty years later, during their second visit they tell us about their experiences and how they overcame many of the societal problems of today.
