‘A promise must never be broken’

Alexander Hamilton

What i understand about this quote is that it's true, a promise must never be broken. A promise to me is like a test of truth. For example if you promise someone to do something, and say you didn't do it, it shows how untrustworthy you are. You shouldn't tell a secret that is something personal that a person should never talk about. You always have to choose the right and not break them. You have to show that you are able to be trusted. You should be careful when you make a promise that you can't keep. You should only break a promise only when it deals with you health and others.
