I can't speak for anyone else but yes, please carry on.

We have a saying in the UK, "I've started so I'll finish".   

Perhaps a few more details between stopping points would be desired. As it sits now, "Would anyone like to know what happened next?" takes up around three fifths of the story.

To reach the main house, the landscape is craggy, on a steep hill, with concrete steps and pathway to climb.
With me, half way up the steps. Opossum, at the top. The marsupial, this wild creature, had the higher ground.

Imagine... What happened next, anybody?

Under a new moon, dark and silent. After midnight, noone else around, except a civilized creature, and a wild creature, which showed no fear.
 
Is anyone eager to know what took place next?

I read through some of Opossum Society site, poor little creatures, it seems they are having quite a hard time. Glad that the sites is there and trying to help.

Gives me some hope 

The email from the Opossum Society of the United States replied, "I'm glad you wish to learn more about this  ancient marsupial.  Our website is full of facts."  Well, one thing I learned is that this marsupial is not a rodent.  

Rather an opossum is a mammal, related to the kangaroo or koala.  When they open their mouth and show all their sharp teeth, that is more or less a bluff which they use as a defense.  It is a wild animal.  You can't pet it or pick it up.  But, in reality it is very, very unlikely to ever get bitten by one.  

As long as you leave opossums alone, there's no need to fear them.  They won't bother you, and they are nice wild animals to have around.  They keep the mouse, and rat population in check.  They eat large spiders too, and they don't remain in the area for too long, so they are not a nuisance.

Oh that's a wonderful story.  Learned something new! All's needed is a good recipe for opossum.
