 Person2:I know that they are auspicious fish . It's quite popular nowadays .  
 Person1:        For God's sake ! It's too bloody . How can people be so cruel ?  
 Person2:Not at all . I think the tattoos are so cool and chic .  
 Person1:        You can't prick the fish to please the sick tastes of some bloody people .  
 Person2:Honey , it's not so serious . It's just an animal .  
 Person1:        Just an animal ? But it has life too . If you want a tattoo , get one . It's your choice because you want it . But has anyone asked the fish if it wanted one ?
