My dad knocked at the door is always hard to knock, knocked, loud neighbors heard upstairs. One night, morning is fear silence in the corridor, dad thunderous knock on the door should wake up the sleeping neighbors. Dad knocked at the door will also shout mom and my name, like a stereo, noisy non-stop.
Mother knocked at the door gently. Mother put fingers bend and knocked gently. "tattoo, tattoo" voice than father well. Sometimes knock on for a long time and no one came to open the door is, mother will ask; "Anybody home?" If no one should be, mother will not be angry.
