Old man lie still

Old man,lie still,lie still      
in peace dank-dark,.     
Those painful years        
disappointed as you,      
a sail, soured before winds      
you should not have trusted.      
On your bike blue and trim      
the costliest you ever owned,      
always setting off against the wind      
looking to an easy homeward ride.      
The mandolin in the loft, round belly        
silent now, once nestled in your lap      
the plectrum woven in the strings      
Silent as once you were    
behind the shy politeness.  
Now I understand.
