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 ?   i mean , most reptiles carry some harmful bacteria . they are likely to cause immune system problems .   well , I didn't realize that .   I don't believe it's a good choice to keep those pets , especially for families with young children .   oh , I should have thought of my brother's baby girl . Maybe I'll just have a dog instead of an exotic pet .   yes , good luck , Maria .
