Cain

It's your birthday, you invited all your friends, your parents prepared a word for you, these friends, so you could sit and spend this birthday properly for half an hour, then first wrote a short message, but with the meaning, "Will you come?" Those who wanted to go online read and ignored, and some immediately left some messages. Your parents cleared the table and you sat in the empty and quiet living room, except for your quiet sobs. Suddenly, someone knocked on the door. You thought it was your friends who decided to joke about you. You, in tears, opened the door and there was Cain, your enemy.
