Some would state; 'A promise is a promise'
I would not say I am against this statement.
To be precise; I am for it.
To be even more precise I have made a promise once or twice before. Probably more than once or twice but to be fair I am not talking about a everyday promise.
I am talking about one of the more rare promises. Those were you are standing in a special situation and are making a promise you are not quite sure you can hold. A promise you after a while notice you can not break. Not just because 'a promise is a promise' but because somehow there is more to this promise than what you thought in the beginning.
You have a memory attached to this promise, so to speak... Or maybe you have something else attached to the promise.
