Do lend a helping hand to each other, especially if you know that a particular classmate has been ill for sometime and had missed school, or had been injured. It will be really nice if you offer some comfort to such individuals.
Do volunteer your time and effort to coaching your classmates who may need your help in explaining certain concepts or homework that he or she is grappling with, even if that person is not your assigned buddy or that person did not approach you for clarification. Just ask, and many a times, you realise your help will be most appreciated.
As a class, do support one another. Truly, one good turn deserves another.
Food for thought!
