Have you ever thought that you are the only person that is always on your phone and smiling like a complete idiot while talking to someone... well you are not the only one.
If you think that just because you do something different or weird and you think that, that does not make you human. That is what makes you human...
Every strange thing we do as a person makes you human because well every other person has done it at least once. The term being human doesn't have a definition: http://dictionary.reference.com/browse/human ( click the link to see the definiton) well it does but what that really states is that your a human if you are part of the human race...
Being classified as a human isn't saying you have two arms and two legs and a head no being classified as a human says that you are part of the giant human race that surronds you every single day of your life.
