How the children would like to spend it is often not how the adults want it to happen! Little Ming and Little Fung are overheard in serious conversation with Granma T. Granma T: Some of the first jobs to be done this holiday are your rooms. They need a major tidying up if Wai Ping and Wah Ming (the workmen) are to decorate ... then there are the files at the back of Mai Ling's office. You pair said that you would sort, label and store them away ... then there is the yard that desperately needs clearing and sweeping and... Little Ming: But Granma, it's our holiday coming up - we have worked hard all year at school. Little Fung: It is time for us to relax, play with our friends, go into town, look around and enjoy ourselves. GT: And get into mischief - like last holidays - remember the broken window? NO. This holiday,work first andplay later! LF: You can't blame that window on us (although we were there) - it was Wai Yenn who hit the ball. LM: And we did not have to pay anything for it! GT: No I did not, but the fuss that it caused! No, you pair will start work the day after school finishes. That is, assuming there is no summer school to go to. LF:Could we discuss this later, Granma? We have homework to do now.. GT: Oh no. Let's sort this out now. Work first. I will re phrase that: Catch up on all the chores NOT DONE then WE consider how to spend the holiday. LM: But we don't want to go visiting relatives and sight seeing. We want to.. GT: ENOUGH...and before you go, help me clear up the clutter from this table. LF: Oh dear, this is not going to be that easy! LM: You are right. Granma will have her way, she always does. LF: But we so wanted to go cycling, fishing and boating this holiday. In fact, I have put our names down to join in with the other students. LM: That won't make a shred of difference - there is a list of chores ... LF: ...that are in Granma's mind and won't go away. LM: Then why don't we start them now and work at them this weekend? LF: Nice idea in theory, but do you want to tidy our rooms NOW? LF: No, I thought not. Come on, let's put the carts away, lock up and tidy the yard ready for tomorrow. We can plot our next move over supper. LM: There ARE no next moves. We have to start all the jobs Granma wants doing and we start sooner not later! LF: Urm four days to go... In the meantime, complete the silhouettes of the lobster, yacht and cyclist.
