Why didn’t billy believe his grand father trap will work I need help please help or imma fail

Billy tries to trap a coon so he can train his dogs with a coonskin, but the coons prove too wily. His Grandpa teaches him to catch a coon with a simple brace and bit, and a shiny piece of tin for bait. Although the coon merely has to let go of the object to free itself from the trap, coons stubbornly hold onto objects.
