as dictionary says, means to feel sorrow or remorse for. A friend says you should not Regret for anything that you do in life. Can it give birth to arrogance or vanquish self-discouragement! Should we or should we not? Is it answerable? Millions of people with billions of thoughts passing by thier minds. Regret is way to find our mistakes. Regret is to stop taking a step further. Confusing is what I can term it as.
p.s.I will try to write something more meaningful next time!
