Cover art for Fire Fire Fire lyrics by Dappled Cities Fly

The part about "tackle with a familiar response" could be something like lust for another that comes easy and when he is presented with that road, his response is the same, and therefore he relinquishes any chance to dance in the fire with that person who is full of life. Now he is left "to burn inside" (anger, remorse).
