Real Housewives star Kyle Richards steps out looking glum after saying she doesn't want to talk about her sister Kim's arrest

Some say 'silence is golden' - and in this particular instance Kyle Richards would probably agree. 

The 46-year-old Real Housewives of Beverly Hills star said she doesn't want to talk about last week's relapse and arrest of her sister Kim Richards, 50.

Though she was seen out and about meeting a friend for lunch, her demeanor suggested she's seen brighter days.

The mother-of-four has had a history of disagreements with her older sister, sometimes leading to a strained relationship. 

Throughout the latest season of RHOBH Kim had insisted she was clean and hadn't fallen off the wagon.

Watching the reunion at the end of the season was reportedly what upset Kim, also a mother-of-four, to the point of going to the Beverly Hills Hotel and later being arrested for a drunken rampage.

Kyle, a former actress and current business-owner, appeared to be doing her best to go about her day and stay focused. 

While being no stranger to the spotlight, the recent events may have had a stronger toll on her than the rest of the Housewives due to her family ties. 

Going on lunch dates and meeting with friends may be exactly what the reality star needed to keep her mind distracted and her actions accounted for.

Her chosen ensemble looked terrific, as she exhibited a nice blend of solids and colors. 

The white button-up blouse rested softly behind a bold multi-colored scarf, framing her neckline as it held a diamond half moon and star necklace. 

Her classic ripped jeans were rolled just above her ankles, drawing positive attention to her lavender quarter heels.
