Possibly an armchair

I was thinking about a monologue Mia wrote about her grandfather in his chair, and remembered that Viv Stanshall has also staked out a claim in this area.

Growing up to be like dad,

Death defying times ahead, 

Retelling stories old,

OF times when dad was older.... younger ...

Now he sits and has

Every comfort and sits 

With a washable cover

Yet it niggles him

That his life has gone by

So he says to his son. 

I don't want to think

I'm not paid to think

I've retired you see

But it worries me

How can I convey?

You might turn out to be

Possibly, an armchair like me.
