Same thing I am going through. My dad is brain cancer striken. He stayed home with me, my brother and my mom. When I Worked my mom stayed guard him. He would sneak out of the house and we would be frantically wondering where he went. Even today when I left for work, he wanted to leave the house with me. My mom snatched the keys and kept them so that my dad wouldn't leave the house when she's busy in the kitchen.
