I gave my parents our Netflix account info back when I was with my ex.
They never used it though. My dad was like "haha now I can see what all you've been watching and mess with your account" and I'm like
".... Dad. I'll kill you."
Using Netflix involves actually getting off the couch and sitting at the computer 'cuz they don't have a smart t.v. or cables to hook up their computer to the t.v.
