All humans are not identical.
You do not play hide-and-seek with dead bodies.
You should not change the colour of your eyes.
These are some of the things the alien calling himself Ben learns when he first comes across a ship full of humans. He has soon read the contents of the entire ship’s computer and knows more about humans than the whole crew put together, but as playing at humans turns out to be fun he decides to stick around for a while. These are the first series of short snippet stories about Ben on board the Bonaventure.
