There may be instances when you don't want to share a status update with all of your Facebook friends. If that's the case, restricting access to a handful of friends—orallowing only a few friends to view that update—is easy.
After you type your status update, click the drop-down menu next to the lock. Choose "Customize," then add people to the "Hide this from" list to block individuals. Or, click the drop-down menu under "Make this visible to" and grant specific friends access to the update.
