 Person1:      Oh , it seems that I'm the only one who never blogs . When did you get started ?  
 Person2:  I began blogging when I first went to the US for my graduate strides .  
 Person1:      What do you usually write about ?  
 Person2:  At first , I'll write about my life there . Like interesting things on the campus , travel stories , special English words that I come across . Sometimes , I'll post my pictures on my blog so my friends and family can get to know how everything's going .  
 Person1:      That's interesting . How often do you write a blog ?  
 Person2:  It's random . If there happen to be a lot of things going on , I may add several new entries in a week , and if I've got nothing to share , I may leave my blog untouched for weeks .  
 Person1:      Got it . Are you still updating your blog ?  
 Person2:  Sure , since I came back from the US , I've been keeping the habit of blogging , simply to share my personal insights on any topic I like .  
 Person1:      Good for you . I know many people just leave their blogs alone after the first few months .
