For this particular post rather than posting the complete poem for a change I thought of posting the video of this poem. I think the importance, the meaning of this poem would be more effective when it is seen, and heard rather than only reading.

I feel you also can connect to this scenario shown by the poet in some or the other way. And hence it becomes very important for us to realise, understand, and bring a few changes in our lives in the future.
