I look at my friend, but all what she does is stare back.I speak to her, but only when I ask a question, she gives answer.I try to cheer her up, she smiles.Than her face looks pained and the smile vanishes as if it never was.It is as if she is hollow, my friend is a zombie.They tell me it is not so bad, I am fun to be around, but I can not see how, I guess my face hides more than I thought.
