Mum: Is anyone home? I need help!
Fred: What are you doing here, Mum? You’re late for work.
Mum: I’m looking for my glasses. I can’t go anywhere without them.
Fred: I think I saw them somewhere Let me look in the living room. Oh, there’s something on the shelf. There they are. Can you see them?
Mum: Fred, when I’m not wearing my glasses, I can see nothing.
Fred: OK, Mum! Here you are! Now you’ve got everything you need.
Mum: Thanks, dear
