This collection of "short fictions and disturbances" is a treat. Just read it.

From Trigger Warning: Short Fictions and Disturbances by Neil Gaiman

"You see, it's almost impossible not to invent the flying car, as soon as you've invented the Lumenbubble. So eventually I had to uninvent them too. And I miss the individual Lumenbubble: a massless portable light source that floated half a meter above your head and went on when you wanted it to. Such a wonderful invention. Still, no use crying over unspilt milk, and you can't mend an omelette without unbreaking a few eggs."
