Then she turned and went into house. She moved very slowly because she was an old lady and she was inside the house for more than 6 minutes and I began to get nervous because I do not know what she was doing in the house. I did not know her well enough to know whether she was telling the truth about getting orange squash and Battenberg cake. And I thought she might be ringing the police and then I could get into much more serious trouble because of the caution.
