      When we're visiting a museum, we can't talk in a loud voice because others are 
all enjoying themselves. To protect the works of art, we should never touch them. If 
there's a sign shows "No photos", we should never take photos. Remember not to 
push in before others. Always queue for our turn. Behaving politely will make us as 
well as others comfortable.
