In your spoken English class, your teacher shows you the following picture. You are asked to describe
the picture and explain how you understand it.
One possible version:
From the picture we can see that one hand is trying to hold the sand with great caution, while the other
hand lets part of it drop.
I think the picture conveys the message of gain and loss to us. The sand is just like good things in our
life. Everyone attempts to get good things and hold them forever. However, it is impossible to keep everything
all the time. Sometimes we have to learn to abandon something, even if it's quite good or useful. In my opinion,
sometimes to lose is not a bad thing, but a wise choice.
