“I have not,” he said. “I have four kids, I live in the countryside. I’m busy either working or taking care of them, but thank you. That’s really kind.”

It was such an intense, weird moment, because I’m watching that video and it’s like eight minutes long, so you’re sitting there and I had just had this amazing, joyful, expanding moment, plus my dad had passed away recently, so [my son] was named after my father… I don’t even know what, really, the word is to describe it.
