We can definitely relate grandfather and Ratna to a horegallu because they helped people in unburdening themselves. A horegallu under a shady tree, sometimes with cool drinking water nearby, lets the people carrying burdens sit for a while and relax, getting back their energy. By talking to the grandfather and Ratna, people also felt relieved, Burdens are lightened when they are shared. In this sense they both are horegallus.
