If you want to make sure you mom can’t see all of your Facebook posts or
if you
want to accept your boss’ friend request without letting them
see your crazy
updates you can hide the update from a specific person or
a list.
When you are about to post on Facebook click or tap on the Public option
-> Choose Custom -> Enter a list or person not to share this with. Keep
in mind that someone else could take a screenshot and show it to them.
You can also add users to the Restricted Friend list that Facebook
creates and
then they will only be able to see things you share
publicly.
