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 and saw one of
them juse 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."
