You would be out clearing your head from a fight with your parents and would head crying in an alleyway and when you went to check it out you saw a little girl with dirty hair and yellow eyes crying looking like she's fighting to survive and when you approached she would look at you and speak in a shaky voice

"Stay back... Or I'll hurt you..."
