Door

Nellie suddenly hide herself behind the wall. "What's wrong?" I ask. She doesn't say a word, but puts her index finger on her mouth: "Be silent!" I hear the door creaking open. I freeze for a second, and then walk towards the door to see what is going on. I see the door opening and closing by the wind, and understand why Nellie is so scared. The door makes her think some stranger is here. I turn and tell Nellie nothing happen. No one is here. "Then what's the sound?" She is still really scared. "That's the wind." I answer.
