 Person2:My mom phoned me this morning , and asked me to go back home to have housework chores . 
 Person1:        What are you assigned to do ? 
 Person2:God knows . Speaking of chores , I would rather do some washing than cooking . 
 Person1:        For me , I think I will iron my shirt and trousers . Actually , weekends tend to be the most hectic day in the whole week . 
 Person2:I really hope that I could sleep like a log all through two nights . But ... Some one said that weekends are a bit like rainbows ; they look good from a distance but disappear before we get up close to them . 
 Person1:        I couldn't agree more .
