You are absolutely right:)
It takes month and year to build a sweet and amicable relation,but it hardly takes any hour to break it.So definitely,it's the words and expressions which define our behaviour and decide our life period of our relationship.
And yes, a word is more powerful than anything in this world.It has two avatars one is bitter and other is sweet.and with bitterness one can break hearts but with sweetness, one can buy hearts of so many people.
So it's up to us, what are we going to yearn for??But I think being sweet is good:)
So say sweet,stay sweet:)
