You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.

 Person1:       Now I know why I split up with Mike . We found we were simply not good for each other .  
 Person2:In what ways ?  
 Person1:        Well , he is a typical Sagittarius guy , while I am a Cancer . We aren't really compatible  
 Person2:Ha-ha , so you believe in astrology ?  
 Person1:        What's strange about that ! As a person born under the sign of Cancer , I am home-loving and wish for a peaceful family life . But according to astrology , Sagittarius guys are too adventurous and risk-taking.They seldom think of leading a settled and peaceful life .  
 Person2:Is that so ? I'm afraid it is too narrow-minded to judge people using astrology . It's all stereotypes !  
 Person1:        But in my case , the fact matches the theory . Mike is humorous , energetic , always as fresh as a daisy , but probably too ambitious . It frightens me !  
 Person2:But as far as I remember , you two caught on like a house on fire when you first met .  
 Person1:        Exactly . But later on , he cares more about his career than love . Work seems to be the better all , and all for him-so much that he doesn't even grudge sparing a day out with me .

 Person1:       My computer isn ’ t running at the same speed it used to be , it is testing my patience everyday . Can you tell me how to make it run faster ?  
 Person2:If you want to speed up your system , you ’ Ve got to clean it up first .  
 Person1:        How ?  
 Person2:You need to free your disk space . The simplest way is to use a Disk-Cleanup tool to remove temporary files and in store programs that you no longer use . Things should be fine next time you start . You also need to control what starts up . There is a program calls Start-up Delayer , It can help to set after how much time programs should be loaded after Windows boosts . For example , you can choose to set your Fox Mail program to load 30 seconds after Windows starts up .  
 Person1:        Very useful advice , I will try them right now .

 Person1:       Annie , what is troubling you ? You look unhappy .  
 Person2:A man is pursuing me . He was my schoolmate in college , and he has been carrying a torch for me for three years .  
 Person1:        Do you like him ?  
 Person2:Yes , I do like him .  
 Person1:        Then why are you hesitating ?  
 Person2:You know that I have had a series of miserable relationships . Last summer , I fell in love with John . But the romance blossomed for six or seven weeks , and then wilted .  
 Person1:        One love drives out another . You shouldn't be afraid to start a new relationship .  
 Person2:Maybe you are right .
