The Question of Sharing a Bed

It was a restless night,

The foot of the bed gave room to curl into a c, nose to tail,  

But no,

In the hours when it is inky black,

You crept,

Onto my pillow

Bit by bit nudging my head off

Until all I had was a tiny corner

To lay my cheek,

And you wouldn’t budge

Out of your deep sleep.

Why do I share my bed with you?
It is simple.
