In the Pet Shop
M r J o h n s o n: Hello!
Could you help me?
I want to get a pet for
my daughter, but I can’t
choose. They all look nice
and friendly.
S h o p a s s i s t a n t:
Get a hamster or a guinea
pig. They are easy to
keep. A lot of people keep
them.
Mr J.: What do they eat?
Do they sleep in a nest or in a little house?
S. A.: They eat grass and seeds and sleep in their cages.
Mr J.: In cages? I don’t want a pet in a cage. I think animals
are born to be free.
S. A.: Pets can’t be free. They can’t live without people looking
after them.
Mr J.: I understand. But I don’t want any pets in a cage.
S. A.: Would you like to get a kitten? We have six wonderful
healthy kittens to choose from.
Mr J.: I don’t know. Cats are not always friendly. They
scratch.
S. A.: A puppy? Dogs make wonderful companions for children.
Mr J.: Yes, but who will take the dog out for a walk? I don’t
think my daughter will do it.
S. A.: Let’s see. You don’t want a parrot, a budgie or a canary
as they live in cages. Would you like to look at these
goldfish? They are really beautiful and fun to watch.
Mr J.: Goldfish? That’s not a bad idea. Could you tell me
about them?
S. A.: They are not difficult to keep at all. Just feed them
at regular hours and keep the water clean. If you look after
them well, they can live a long life.
Mr J.: I think I’ll get one and a fishbowl for it. Thanks for
your help.
