A mother planted many kinds of vegetables in her garden. One morning she said to her daughter, "Betty, come here. Look at all these little yellow marks on the leaves of the cabbages. They are eggs of a kind of insects. They are very beautiful but very bad for cabbages. This afternoon you must find all the eggs on the leaves and kill them. In this way, you will help us have better, greener and bigger cabbages.
Betty didn't think she should do it at once and in the end she forgot all about it. Her mother was ill for a few days and couldn't work in her garden. When she was well, she took Betty to the garden to see the cabbages. To their surprise, the insects had eaten up every leaf. When Betty saw this, she was upset and began to cry. Then her mother said to her, "We should never put off what we have to do today till tomorrow. And you must learn to deal with the things while they are small, or it will turn into a big problem."
