Granted, It's *possible* that there could be a *truly* "alien"
situation here on this planet between two mammals.
But considering the extreme correspondence between different
mammals, including humans; the amount of relatable points we
share FAR out weight the differences.
Example: dogs and cats.
They're really almost alike. They also learn to tolerate each
other. They also have ways of communicating with each other.
Consider that: *we* can't penetrate the minds of dogs and cats,
yet, they still communicate.
