Lucy: Hi, Mike. What did you do yesterday?
Mike: I cleaned up our neighbourhood with my brother.
Lucy: Er... Many people throw rubbish here and there. What do you often do with rubbish?
Mike: We usually put rubbish into different bags. You know some can be used again.
Lucy: Well done! I should learn from you and do as you did.
Mike: How about putting a notice with the words "Don't litter!" in our neighbourhood? Then it can remind others to keep our neighbourhood clean.
Lucy: Good idea! Let's do it now.
Mike: OK!
