Many things are just the same.
You still need to get on
with the physical business of living.
Eat, pee, sleep, wash, and so on.
Do the dishes, put the dishes away ...
observe the normal routines
that made the household function
for two — as it must for one.
You'll notice you still cook dinner,
still read, watch television, feed the cats,
sit at your computer, write ... do all
that you did before with company.
There is basically only one difference —
and the many small changes
which follow from that. Some you like,
some not. They may be the same.
You spread out in the double bed (you
and the cats). That can be luxurious
or bleak. Taking the other chair, not
to see it empty, you find it better placed.
No-one (except for those cats)
will nag you now for meals, or when
to come to bed. Be thankful for the cats!
You too need food. You need sleep.
At first you may decide and plan
activities your Other would have liked,
things you believe they wanted.
At this point heed the wise advice
your son the other day returned to you,
which he says you gave to him
decades ago, after his father died: 'Don't
live someone else's life; live your own.'
