Whenever someone asks me whether I have a Facebook, simply I respond with ''No''.
Having a Facebook page and not having use for it is like;
Having a garage full of tools, but no knowledge on how to use them.
Or, like having a wine cellar, but not even drinking wine.
Useless. :3
People that require you to have a Facebook in order to socialize with you, aren't your friends. There are still people without internet, or even computers, let alone a Facebook. You're just fine, and just as wonderful without it. ;3
