the king size bed

at first,

it's a small rocking

cradle of some

sort

that holds you.

then a crib,

a happy cage of sorts,

then

a day bed

by the window, but

still with

bars so that you don't

fall out

and then

the twin bed

when reaching school age,

the dormitory slab

or single bed,

eventually a double

bed or queen

when you're on

your own,

and others might join you

in sleeping,

and at last

when you have the money

and the room

to put it in,

you graduate

to king.
