Nighttime Drama Queen
Photo 1:
Playing Possum
While taking out recyclables at night, I heard something in my backyard. Got my camera, turned on the flash and discovered a small possum foraging in the leaves. I said hello as I took this shot & it promptly fell over and played dead. Complete with the mouth held open in a "death rictus"
Photo 2:
Is She Buying It?
I stayed still & quiet and soon the possum cut its eyes over at me like it was checking to see if I was buying its act.
Photo 3:
Cautiously Getting Up
Very slowly the possum started to get back on its feet.
Photo 4:
Still Showing My Teeth Just In Case
As it began to sit up, the possum kept the death grin going, just in case there was still a threat out there.
Photo 5:
And....I'm Dead Again!
I made the mistake of saying "it's ok baby, I'm not going to hurt you" & the possum promptly flopped over and froze. "Dead" once again. I was chuckling as I went back inside so the little drama queen could go about its business.

Robust vine. I think this is the native W. frutescens rather than W. sinensis or W. floribunda. I found a source suggesting that sinensis and floribunda have fuzzy/velvety seed pods while frutescens is smooth. Observations on iNat seem to bear out this distinction. Also, the seeds on this specimen look bean-like, while most of the photos I saw of seeds for the other two are flatter and rounder.
