Cry from a Far Planet

"A smile of friendship is a baring of the teeth. So is a snarl of menace. It can be fatal to mistake the latter for the former."


"Harm an alien being only under circumstances of self-defense."


TRUST NO ALIEN BEING UNDER ANY CIRCUMSTANCES.


--From "Exploration Ship's Handbook"


The problem of separating the friends from the enemies was a major one in the conquest of space as many a dead spacer could have testified. A tough job when you could see an alien and judge appearances; far tougher when they were only whispers on the wind.
