Hi , Sam . I want to buy a pet . Do you have any ideas ?   You really should go to Rachel's pet store .   Why ? anything special there ?   It's more than special . You can find as many kinds of animals as you can put a name to and more .   Oh , really ? are there any snakes ?   Snakes ? there are even rodents and monkeys ! it's a world of exotic pets .   That's terrific . I can't wait to check it out .   Hang on . are you sure you want to keep a non-traditional pet ?   Why not ? it's so cool .   But it will pose a risk to your health .   Pardon ?
