There are people who say "NO" without knowing why they are saying it. They say it just for the sake of saying it. Or sometimes they say it out of emotions especially when they feel hard about something though they still cannot explain why they are against this or that. If there was no WHY in this world, donkeys would have been wise enough to lead or teach at the International and local universities

N and O are two letters
In the English alphabet
They sit side by side
They are good neighbours

When you add them up
They make the word "NO"
So light it is to write
So heavy it is to say

While O is coughed off from the throat
N is scratched from the roof of the mouth
Your tongue would press the ceiling
And so it gets ejected from its seat

Different people say "NO" differently
Some say it as a way of assertion
Others say it as a way of defence
Some others say it as a way of rejection

It is everybody's right to say "NO"
But you cannot exercise it as you wish
Say “NO” only when you know "WHY"
Otherwise ............
