Sister:Tony,could you please help out with a few things?
Brother:Could I at least finish watching this show?
Sister:No.I think two hours of TV is enough for you!
Brother:Fine.What do you want me to do?
Sister:Could you take out the rubbish,fold the clothes and do the dishes?
Brother:So much?
Sister:Yes,because Mom will be back from shopping any minute now.And she won't be happy if she sees this mess.
Brother:But the house is already pretty clean and tidy!
Sister:Yes,well,it's clean,but it's not “mother clean”!
