It all (happen) one winter night at eleven o'clock at night. The bell (ring) and mum (go) to open the door. At first, she (not see) anybody, so she (close) the door. A minute later the bell (ring) again. This time I (go) to open the door and it (be) my neighbour. He had slipped on the snow the first time. He (want) to ask us if he (can) stay with us because he (not have) either light or central heating and he (be) really cold. Obviously, he (spend) the night with us and he (sleep) on the sofa.
