Innocence returning (Edit 1)

[Wjames]

There’s a cold breeze
coming through the back door I think you could cut "coming".
causing it to creak on its hinges,
Grandad's gone across the backs I assume backs is referring to back yard - [b]are there multiple backs? I might just be missing something.[/b]
to feed his pigeons.

I find him inside the empty loft
closing derelict cages,
gently I place an arm
around the confusion. I like this "I place an arm around the confusion". I don't know if you need "gently", though, the context implies you're trying to soothe the situation anyway. Plus, "soft words" in the next section confrims it.
Using soft words we stumble outside
towards real moments. I think you could have something stronger than "real moments".

The overgrown allotment glistens
through droplets, strung out
to tremble in the damp morning light.
We hear the rush of racing pigeons
and watch them disappear overhead
like ghosts into field mist. Nice.

Grandad stood staring at the sky,
“they’re not coming back are they son?”
I put my coat around his shoulders,
‘no Grandad they’ve been gone too long”.
We start the slow walk back towards the house.

“Someone will have to tell your Grandma,
she loved those birds”
“She’s gone too Grandad,
Grandma’s gone too”.

This poem's not for the birds. I liked it, it's a nice scene.
