There are many various types of morphological properties of radio galaxies and it remains unclear as to what causes these differences. Do the intrinsic properties of the central engine (‘nature’) mold and shape the radio source? Do the properties of the surrounding medium of the central engine and host galaxy (‘nurture’) cause these differences? Settling this ‘nature vs nurture’ debate for nearby radio galaxies will provide clues to the properties and evolution of radio galaxies throughout the Universe. In this talk I will present NGC 612 and provide evidence for interaction between the radio-lobe hot-spot and the HI bridge connecting NGC 612 to NGC 619. I will discuss the importance of lobe-HI interactions for the morphology and dynamics of radio galaxy lobes and the host galaxy.
