The actor spoke candidly about the experience, sharing that"I'm a girl dad. It's so interesting because [I'm] always wanting to have my own experiences and not live in the shadow or follow in the footsteps of somebody. I get the experience of being a girl dad. I feel like having daughters is such an incredible privilege."Lowe then reflected on how fatherhood had shifted his perspective on the world his daughters are growing up in, adding that"I know that there are struggles. And now it's taken what I've known intellectually, and it's put it in my heart because I now have three daughters. And so, I look at the world from really their perspective and I see the world and a lot of the injustices in the world from their perspective."That being said, Lowe was quick to point out that he remains hopeful. He explained that"It's not all doom and gloom. Society is changing. I see how we're really becoming conscious of the role of women. We may, who knows, have the first female president."He concluded on an optimistic note, adding that"[We're] really empowering women and seeing how much women have to offer. I personally think that if women were in charge of nations, we'd be a lot more peaceful."
