“A promise must never be broken”

          -ALEXANDER HAMILTON

what this quote is trying to say is that a promise is a promise and you should not break that promise because had done a pact. And if you break the promise now some people will not believe or trust on you because you had done a promise and broke that promise. You have practice for dance classes and you tell coach “i promise that i will be their” but then you can get on time because the bus will arrive late so you just don't show up you just had broke that promise to yourself and your coach. But if you had send a text or called your coach that you were going to be 15 minutes late because the bus will not arriving on time and he accept it you had not broken your promise. “ A promise must never be broken”
