We want to see what it's like3My grandmother thought that they looked like nice gris so she invited them in They looked round the living room and then one of them said Can I have a glass of water please? so my grandmother took her into the kitchen While they were in the kitchen she heard the other one run upstairs4What are you doing up there? she shouted and the girl said Can I use your toilet please? My grandmother said yes and didnt worry about it although the girl was upstairs for ages She gave the girl in the kitchen a glass of5My grandmother didnt notice anything at first, but when she went to bed that evening she found that her jewellery wasnt in the usual place And then she remembered the girls and called the police They were very sympathetic but I dont think they'll ever catch the girls
