Will just,"Thank you, Sir" be enough?

                                    My teachers,the greatest godsend gifts on earth,
                                    Burning your candle to light the lives of zillions of us
                                    Without you,my gracious teachers of all-time,
                                    Dead would have the best curriculum remained.

                                   Your teaching of being innovative and creative was
                                   Really an oasis in the deserted life of mine.
                                  You educated me not just to think what's in the box,
                                  But at times to think outside and some days without it.

                                  You have withstood the storms and thrown your shadows,
                                  Upon a small saplings which now shakes before the breeze.
                                  You even irrigated the dried corner of my life,
                                  After you were sure that my bushes of illusion are cleared.

                                 Much good light in life have i learnt and realized,
                                 For you have stood by my side despite my hiccups.
                                No pearls can speak how grateful i am nor will do so,
                                For you have created "amazement" beyond anyone's dream.

                               And today the day has come for you,my dear teachers,
                               To make you feel how amazing you are to the world.
                               World is selfish for having kept only a day as,"Teachers' Day"
                              But you you already know that every day is your day.
