     We had guests last night who have not stayed     
in a B&B hotel ago. They did not want breakfast  
because that they were going out early in the     
morning. They came back lately and had some     
tea. I came into the living room or saw one of  
them just go through the kitchen door but turn   
on the light. He was looking for a glass the    
cupboard. He had no ideas that the kitchen was   
not for guests. I just smiled to me and thought, 
"What can I do? We are guests after all."    		1______
