Time is like a pushing hand, pushing our youth forward. From ignorance to youth, to waving to youth with a smile, youth carries so many beautiful memories of us, quarrels with parents, play with classmates, growth with oneself, battles of wits and courage with teachers... My teacher is very "two", and records the stories of our battles of wits and courage with teachers in written form. You may be able to find your shadow here, your teacher may be seen here, and you may see a different teacher here.
