Defending You

I made no effort to explain the joke,
Or help you understand what made us laugh.
I didn't intervene on your behalf,
Stand up for you, or offer you a smoke,
But when you missed the point, two of them spoke,
In whispers, saying you would need a graph
With legends up and down the left-hand staff,
And I suggested calm. Then the dam broke.

They seemed to think I was defending you.
I'd never do that. I don't like you much,
The way you use depression as a crutch –
You're not depressed; it's just an avenue
For self-expression, isn't it? What's new
Is that I'm laughing. Not at you, as such.
