At the end of Standard One in 1962, my kampong neighbour and good friend, Mike, came over and asked me if I could pass on all my textbooks to him (he was one year my junior).
Well, we were all poorer than church mice then. However, the good old neighbourliness spirit kicked in, and gladly I passed him my early childhood inheritance (with full approval of my parents).
One good turn deserved another. After Mike finished his Standard One, he passed “his” textbooks to his younger sister (one year his junior), and lo after she was done, she returned the entire heirloom to my own younger sister. Of course by that time, many dogs had left their ears on many of the pages, with an occasional paw print here and there.
This Re-use and Recycle practice went on for several years
