[其他] 帮忙想想如何解释

今天念了一个小小故事给儿子,如下:
little red hen had a bit of wheat. "who will help plant?"said hen.
"not i," said dog. "not i,"said pig. ""not i,"said cat.
"i will go to the well,"said hen."who will help me get some water?"
"not i," said dog. "not i,"said pig. ""not i,"said cat.
"this is a big job,"said hen."who will help me?"
"not i," said dog. "not i,"said pig. ""not i,"said cat.
"i will mix and mix,"said hen."who will help me do this?"
"not i," said dog. "not i,"said pig. ""not i,"said cat.
"come quick!"said hen."look at this bread!""this is thebest bread," she said."who will help me eat some of it?"
"let me," said pig. "let me,"said cat."let me,"said dog.
"no,no!" said hen. "this is a job for me!"
看完后儿子对文章表面意思理解的,但是他给我的总结是母鸡太小气了,不好.
我告诉他只有勤劳的人才能有收获,懒惰不愿劳动的只能饿肚子.
儿子说:如果在我们语文书里的话,到最后还是会同小伙伴分享的.
我想了半天怎么解释呢?他说的也没错呀.那母鸡到底是好还是不好呢?.

当然母鸡是对了。这就是外国故事和中国故事的区别。这里告诉小朋友：没有劳动，没有享受。社会上就是这样的。天下没有免费的bread..

谢谢。我还想问问"not I"语法怎么解释。我自己搞不清是i 还是me.
