when a no says it all

yes or no have been such an inevitable part of any language but strangely they aren't under any parts of speech!!at least i don't know and havent ever been told about there belonging to any part of speech. Seems they cannot be put into any and are a part of speech on their own.Further this NO amuses me more sometimes because of its laconic attitude.....for a yes opens a whole new world of possibilities, opportunities,chances of success and failures, speculations, plans,fortunes ,misfortunes,apprehensions, fear and so much but a no says it all and ends it all then and there...for construction or destruction...but it says it all.It dosen't leave scope for any further argument and ends all that a yes would have opened up....so laconic!!
But its not only the laconic attitude thats appealing about a NO....but also that psychological element surrounding the word is noteworhty.British Prime Minister, Tony Blair, once said " The art of leadership is saying no,not yes.It is very easy to say yes". Infact saying no is an art in itself.An art that has no comparables. In life we face a myriad of situations where saying no is not only inevitable but also mandatory. Generally no is always accompanied by a degree of sternness that depends upon the situation and the person on whom the no is to be crowned.For eg. when a mother says no to her child's demand for candies- the no is so full of concern or so full of guilt if the demand is unaffordable for her.But when a woman says no to a man's lustful advances or even to a sincere proposal which can't be reciprocated for some reason of her own there isn't any concern or guilt but a sense of self respect and also fear that need not be explained.But in both the situations it is a rope walk and that is where the art lies.In the former case the care is to be taken that the feelings of the child is not hurt while in the latter the feelings are to be destroyed without hurting the ego.Again in both the cases the no should be so artfully accompanied with the apt degree of sternness so that the demand and the proposal is not repeated. What an art!!
But saying no is not always such a grave situation.Just imagine a situation where a renowned glutton is saying no to a plate of sweets offered to him. It is a funny one.If you get a chance do try to notice the urge in every limb of his to snatch that yet he is refusing with utmost will........This no dosent end with just a one no 'cause the host does press it to the guest to have it and now it depends on how determined that no was(will continue further)
