It’s safe to say thatKyle Richardsdidn’t experience your average childhood.

Appearing onMegyn Kelly Todayto promote the show on Tuesday, Richards opened up about one of the plot points of the very first episode: how her mother found out that her husband — Richards’ father — was cheating on her.

“She opened a checking account for me,” she continued. “She wanted me to take control and learn from a young age how to look after myself, because she didn’t like finding herself in that position in the ’70s. … It’s not easy being a single mom, whether you’re in the ’70s or today!”

In fact, Richards said the entire series is “a love letter” to her mother.

“My mom was a very strong, outspoken woman and in that time, women weren’t supposed to be like that,” she said. “Now it’s like, ‘boss lady’ — that’s a term now. But in the ’70s, if you were strong and opinionated and outspoken, it was looked down upon. And my mom was that woman — very strong.”

Richards, 49, also touched on the tensions that arose with her older sisterKathy Hilton, 59, after Hilton got the impression that the show would be too personal.

Speaking to PEOPLElast month, Richards said she would “never tell anyone else’s stories” and certainly “would never do anything to disrespect or embarrass” her sisters.

“Every family has their moments, but we’ll be fine,” she added. “I love my sisters, and that’s all that matters.”
