     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."
