Suzy: Welcome. May I help you?
Lizzy: Yes, I want an eye-shadow.
Suzy: We have different colours of eye-shadow. May I know what colour you usually wear?
Lizzy: Purple. But today, I'm thinking of buying one in a bright colour.
Suzy: Yes, I see. How do you like this one?
Lizzy: May I have a try?
Suzy: Certainly.
Lizzy: It's still too dark. Any brighter colours?
Suzy: Not from this brand, I'm afraid.
Lizzy: What about other brands?
Suzy: How about this one?
Lizzy: Oh, that's the very thing I need.
Lizzy wants an eye-shadow in a bright color, and Suzy helps Lizzy choose one that Lizzy's satisfied.
