Trope-a-Day: Innocent Aliens

Innocent Aliens: Not very many, no, and certainly not the full extent of this trope.  Evolution is rarely kind enough to produce a planetary environment that lets anyone this wide-eyed and innocent survive for long.  And even on the rare occasions that it might, the greater Galactic community includes plenty of people who will, ah, help them, in many ways in which they probably did not wish to be helped.

This is, of course, horrible, but nonetheless pretty much also is.
