Welcome, once again, to the beautiful Sinclair family.
We believe in outdoor exercise. We believe that time heals.
We believe, although we will not say so explicitly, in prescription drugs and the cocktail hour. (15.1-3)
Even though the Sinclairs know each other inside and out, Penny still lies to Bess and Carrie about Cadence's medications. Nobody would fault her for taking the addictive stuff, but Penny insists on pretending the non-addictive pills work—so yeah, the Liars aren't the only ones who lie.

Now, at the breakfast table, watching him eat my toast, "Don't take no for an answer" seemed like the attitude of a privileged guy who didn't care who got hurt, so long as his wife had the cute statues she wanted to display in her summerhouses. (42.21)
Granddad tells Cadence not to take no for an answer, but, on his usual huge power trip, denies her even her own toast. He's basically saying, "Don't let anyone tell you no. Oh, you want that breakfast? No. Psych!"
