Kylie Jenner and her sister Kendall grace the cover of Sunday Times’ Style magazine now. In the interview that accompanies the shoot, the sisters weigh in on the biggest problems in their gilded lives. For Kendall, it’s phones.

“I think social media has taken over for our generation. It’s a big part of our lives and it’s kind of sad. I hate it sometimes, like, I literally want to throw my phone so I can’t look at it. It’s all a made-up world if you think about it. Social media, everything, this interview, everything. It’s not real. It’s pretty crazy.”

Kendall Jenner gives a specific example of how her phone intrudes on her life and how she deals with it.

“We had a two-hour drive from the airport to where we were staying, and I’d left my phone in my bag, so I didn’t touch it the whole way. I looked out the window at everything, and I saw people who live in huts and have dogs that were, like, withering away. And all their food, meat, was hanging in front of their house. It was very sad. Then we pulled up to this amazing house we were staying at, and I looked over and Kylie was on her phone the whole time and didn’t see one thing that I saw.”

She said the experience was “super eye-opening, because you’re seeing what’s happening, and truly, truly real, right in front of you.”

As for Kylie Jenner, she is afraid of growing up.

“I’m scared of the day I turn 19,” Kylie said. “I really don’t want to grow past 18.” Looking at her sister Kendall, she added, “You’ll be 20 this year – that’s crazy. And any second you’ll be, like, 21, 22, 23…”

“It’s scary. Life is scary. It’s just scary how fast everything is rolling and you can’t stop it. It’s rolling right now. You see a picture and you’ve changed so much in a year.” Kylie added, “I’ve done so much, physically and whatever.”

As for her take on social media, Kylie Jenner is matter-of-fact.

“Instagram is a made up world. I just show people what I want em to see. Doesn’t everybody?”
