Now this is the part where you will decide exactly who does, and who DOESN'T see your post. Click on "edit" next to "Custom." Another window will appear like this:
Now, you will notice a convenient text box for "Hide this from." In that box, type the names or the group of people you want to hide the status update from, then click "Save Setting."
