Winner and Loser

Man in a suit drives his Rolls Royce, Kept polished shinning by local boys, His scarf and cravat are made of silk, His designer trousers as white as milk. Knows full well his source of wealth, Keeps me nourished in prime health, Well clothed and housed in my room, Cared for fully by a personal groom. Many a Cups and prices I have won, He takes the applause when I am done, He has amassed gold and diamonds, My earnings merely grass and almonds! How long will this love and dove last? Will he care when I am no longer fast? Will he remember me, his source of bread? Or will it all end with a bullet to my head?
