Nests

Nests are such wondrous things:
     birds make them of twigs  
Did none ever tell them about the big bad wolf
     He doesn't climb.  
Some make them of lint and fur and cast-away stuff
     Lives can be made of those too.
Sometimes I think Mine was
                                         flotsam and jetsam  
carried on a wing and a prayer
     who wrote those Lines
And where did They get the courage
     Did Some change the words?    
                                             I changed the record;
Pleased and sated now I am.
