I watched a TED video about Adora Svitak. What comes to your mind when you think of a word 'childish'? Immature, or short-thinking right? Many people think adults can not learn from children.  But Adora thought differently. She thought that adults children can learn from each What is my opinion? I agree with her opinion. I think adults and children should learn from each others.
 First, adults lived longer than children, so they know much more than children do.  So adults can teach children many knowledges that children don't know. If adults teach children, children can have wider knowledge. Adults are good teachers to students.
 Second, there are many things that adults forget while they grow up. As people become older, and become adults, they forget what they used to do, and what they knew. For example, playing. When children becomes students, they rather read books than going outside and play. They become mature and stop theirselves from playing.
 For these reasons, if adults nd children learn from each other, then both will learn many things.
