But
it's
the
hоuse
I
wаnt
tо
tаlk
аbоut,
the
house
and
Irene,
I'm
not
very
important.
I
wonder what
Irene
would
have
done
without
her
knitting.
One
can
reread
a
book,
but
once
a
pullover
is
finished
you
can't
do
it
over
again, it's
 some
 kind
 of
 disgrace.
 One
 day
 I
 found
 that
 the
 drawer
 at the bottom
 of
 the
 chiffonier,
 replete
 with
mothballs,
was
filled
with
shawls,
white,
green,
lilac. Stacked
amid
a
great
smell
of
camphor‐ it
was
like
a
shop;
I
didn’t
have
the
nerve
to
ask
her
what
she
planned
to
do
with
them. We
didn’t
have
to
earn
our
living,
there
was
plenty
coming
in
from
the
farms
each
month,
even
piling
up. But
Irene
was
only
interested
in
the
knitting
and
showed
a
wonderful
dexterity,
and
for
me
the
hours
slipped
away
watching
her,
her
hands
like
silver
sea‐urchins,
needles
flashing,
and
one
or
two
knitting
baskets
on
the
floor,
the
balls
of
yarn
jumping
about. 
It
was
lovely.

Whаt is the аverаge tidal vоlume fоr adults (male)?
