Answer on 10 points!!!! only if you know a lot about facebook privacy settings?
You can set your privacy settings to "Friends of friends" which the first girl did.
You can also set it to friends only , which the second girl did.
You can also customize it , so you can block people who youb don't want seeing your profile.
