Every little sound, she jumps, every small sign of life didn't sound like life at all. She kept hearing the word "Siren".
What siren? What is a siren?
She goes to the door of one of the buildings and knocks on it.
"Hello? Can any one help me? Hello?" She tries the door handle and it won't open. She goes to the window, knocking on it. "I can hear you, please, can any one tell me how I can head home? Please even a phone would help."
