Ladies in Snow

The image is this week's prompt from Magpie Tales

Seeing that, I'd like to be a sculptor. I would sculpt
this group of ladies ploughing through the snow.
They're perfect as they are: no need to recompose.
There's one who carries keys, large keys... the keys to what?
A church perhaps, and she - and they - are on their way
to open it. But one is wearing... wearing what? A golden chain?
A chain of office? Gold medallions? (Horse brasses
sprang to mind. But no, scrub that!) The Lady Mayoress
perhaps... but why would she be openinng the church?
They must be off to open some new pile in some
official role. They'll cut the tape and make a speech,
declare it well and truly open from now on. All that,
my dear, in snow, for snow lies everywhere. But now
the smallest lady of the group has pressed
her lips together in a long thin line. She is resolved
that she will press on, just behind the other two,
and come what may, fulfill her... what? Who knows!
But I, if I would model them in clay, would find
the clay confronting all these issues. Clay is soft
and answers every question. Begin then, with the biggy
and all the rest are given as you go.

The biggy is the unity that binds them all together.
Could they be sisters, friends - or lovers? Aunts
and niece - or strangers thrown together
in adversity? They might be ladies bountiful from church
or chapel, off to do their bit - perhaps the keys
are to the village lock-up, have been borrowed; and
the three are on their way to save the lost souls there?
These are the questions I could answer in the clay.
