Kendall and Kylie Jenner are not ready to enter the world of grownups. The famous sisters think being an adult can be scary.

In an interview with the Sunday Times’ Style magazine, the Jenner sisters shared the common fear of ageing. The two, which are featured on the magazine’s May 31, 2015 cover, were quoted to have said that they believe life is scary, especially for adults. Kylie, who is currently 17, said she does not want to turn 19. She said she does not want to grow past the age of 18. She even said Kendall turning 20 this year is “crazy.” She is also incredulous at the thought that Kendall would turn older than 20 as the years pass.

Kendall agrees. Being 19 now, she said it is “scary.” “Life is scary,” she added. While they seem afraid of growing up, the sisters do not have a shortage of “adult” responsibilities. The two are currently nourishing their respective careers as well as the fashion lines that they have worked on together: Topshop, Pacsun, among others.

In an interview with Vogue AU, the duo talked about designing clothes and living in the public eye, ever since they were little kids because of their family’s reality show “Keeping Up with the Kardashians.” The sisters shared that working for Topshop and doing a line for the brand is really cool since the brand is a big fashion name and a lot of people love it. The two are keen on making Topshop consumers love their line, which they said are inspired by the LA girl. "We’re trying to bring the LA vibe to Topshops all over the world. We were thinking about the LA girl, who she is, what she loves to do and what her dream capsule wardrobe would be,” Kendall said.

On the same interview, the two also shared that becoming aunts to baby Reign is the highlight of 2015. Kendall added that she is happy that her career has really taken off this year. Both showed that they have great responsibilities, even at their young ages. Asked what it feels for them to grow up in the public limelight around TV cameras, Kendall said it opened so many opportunities so they cannot really complain. Asked though what the best thing is about being a teenager, Kylie again claimed that she does not want to get past 18 and that she is only trying to live and enjoy every moment now.
