You see, I don't like long poems 
My attention span is not so long,  
And the birds are busy through the window;  
I'm so afraid I'll miss their song. 
 
Birds don't last long, in this world,  
As my mind grows shorter than a fuse,  
Lit at the business end of a stick 
Of dynamite, and that's no ruse. 
 
You see, I don't like long poems;  
For I'm growing older by the clock 
And I've things to say to this old world,  
And tombstones aren't well known to talk. 
 
I've things to say, and people's eyes 
Are wandering, while I have my say;  
Seems I talk faster all the time,  
Before the light runs out of day. 
 
You see, I don't like long poems;  
My shadow's shorter every year 
I don't have endless hours to read- 
There's words I'd really rather hear.
