We both saved our faces

A  lady   loses her  leg, shoe on,
from half way up in the street car.
The artificial limb simply slides down.--
Before it reaches the pavement,
I manage to catch it.  I hand it to her.

Leaning against the left door  flap,
she swiftly  fits it back on.
And sends me a smile
as the tram leaves.
And I smile back.
