How can I hide my "Wall-to-Wall" on facebook?

How do I hide hide facebook activity from certain people?

• I saw my dad looking at his facebook the other day, and he doesn't have many friends, so basically any activity that anyone does, he knows about it. Like if someone likes a link that someone posted or a picture, or if someone comments on a status, he sees it. And usually, this person is me, and I'm constantly being questioned about it like "Why were you looking at this picture?" or what not. Anyways, I just need to know how to hide all that activity from him.

• Answer:

  If you're using timeline format click the arrow in the top right hand corner and go to privacy settings. Next click on the custom button and where it says "hide this from" and type in your dad's name and then save.
