Lost property

You must have
left her with me
by mistake

maybe you put her down
to pick up your coffee cup

many years ago
when we were younger
and less careful

we sometimes let
our paths cross
with those of strangers

as if we didn't know
the dangers

I've tried not to
let myself think of her
as mine

but I've become used to
having her around

she's grown a little wiser
over all the years
I've kept her

just in case
one day you
want her back.
