National flags are patriotic symbols with varied wide-ranging interpretations, often including strong military associations due to their original and ongoing military uses. 
 During the days of my childhood till now, I have  notice the disdain look of the  Nigerian flag . Which fly in public and private institutions,you will agree with me that 80% of this flags are mistaken for rags. Sometimes when I see it, I ask my self if am in the country called the most populous black nation earth. 
  Well it's due to this that you notice in our country  the lack of patriotism, tribalism, nepotism, injustice, inequality, self denial by the leaders, corruption and many others.
 In my own view, I feel  only GOD and  a few adults and babies that can put this country back on track. A famous quote by Frederick Douglass "It is easier to build strong children than to repair broken men" 
   As for the only way to change a flag is to make a new one with different materials .

Rightly spoken my brother.
