Answer:
if you let others use you for your own purposes, they will also use you for their own.
Step-by-step explanation:
In the story "The Horse, Hunter, and Stag", the horse in an attempt to take revenge on the stag agreed to let the hunter put a piece of iron in his jaw and a saddle on his back so that the hunter could kill the stag.
However, after the stag was killed, the hunter refused to free the horse but instead wanted to use him for his own purposes. It reminds us that if we let others use us for our own purposes, they will also use us for their own.
