It seems Robin Williams' family are coping the best they can following the beloved actor's untimely and unexpected death last August.

On Thursday, Nov. 20, the late comedian's eldest son, Zak Williams, spoke in public for the first time since his father passed away and shed some light on how his family is adjusting to life without Robin.

"We're doing okay," Zak, 31, said, speaking on behalf of his half-siblings, Zelda, 25, and Cody, 22.

"We're acclimating to the new normal. Everything is step by step. Personally, my wife and I are focusing on doing a lot of good. She runs the San Francisco office of Human Rights Watch, and we're working with them to do good in the world," he said at the Christopher & Dana Reeve Foundation gala in New York City.

"Dad had almost a childlike love, and he shared that love with people, with everyone," he told Us Weekly of the admiration Robin felt from helping others. "And that ability to love, and that ability to be generous and giving and kind is something we would want to share with future generations."
