Input:  Person1:       You look a bit dull today . What's up ? 
 Person2:Well , my mum lost her job yesterday . 
 Person1:        I'm sorry to hear that . Well , I heard that registered urban unemployment rate reached 4 percent this year , with more than half being women . 
 Person2:The supply outstrips the demand in the job market and women are in a disadvantageous position as a whole . 
 Person1:        Yeah , it's true . What is she going to do ? 
 Person2:Well , she is thinking of doing some household cleaning or baby sitting in the community . 
 Person1:        That's not bad . It could be a short-term alternative . Your mum can look for another one when the market improves . Things will work out eventually . 
 Person2:Thank you . I just hope she won't feel pressed .
