测测你的词汇量是否不如小学生？【APH】

路人测词汇，养老人吃粮～小学生都看得懂的纯天然无公害绿色文章，文笔？那种东西不存在的。
（因废话过多被打）
This is my friend,Peter. He is very helpful. But, he is very old now.
He has a friend. His name is Arifred. Arifred has some friends too! But, sometimes his friend doesn't look like him very much. Because Arifred sometimes is very noisy, his friend doesn't like him? This is ordinary.
 Oh...
 But... 
Peter is old, but Arifred is very very young.
He is sad, but Arifred thinks it is ordinary.
"Why are you happy every day?" Peter says.
