Ellen Pompeo's daughter has hilarious message to those trapped with siblings

"Social distancing 101 from Sienna May."

It's all fun and games until social distancing gets extended for another month -- just ask Ellen Pompeo's daughter Sienna May.

The 5-year-old took a minute to vent to her mother about how her 3-year-old brother, Eli Christopher, was getting on her nerves, which the 50-year-old actress shared with her followers. Pompeo posted the video Sunday in an Instagram post captioned, "Social distancing 101 from Sienna May #micdrop."

"He is so rude and it's just ... he keeps testing me," Sienna explained in the adorable clip. "Eli, he keeps testing me. Even when I was 4, he [kept] testing me and even now that I'm 5, he [is] still testing me. Every day he is testing me."

When the "Grey's Anatomy" star -- who is also mom to 10-year-old daughter Stella Luna -- asked what they should do about the situation, Sienna responded, "We should separate." An idea that Pompeo was fully on board with.

"That's great idea," she agreed diplomatically. "Separate."
