        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.
