Go....?

 It goes without going

It says without saying

It means many things

Like I’ve had enough

Or stop

Or start

It’s a kind of art

It is, it’s on, it’s off

The chart

I can bring it on a tray

It’s how I feel when I’ve too much to say

But can’t

Sometimes I feel I’m going to

But it’s the thinnest membrane

It’s always after something gives out

It never really gives in

It’s an excess of nothing

And something to begin

So don’t put your hip out

Or you’ll need to shout

Weasels do it

Pringles do it

Even the blisters

Of measles and shingles do it

Let's do it

Let's go......?..........apart
