“ A promise must never be broken”  

~ Alexander Hamilton

What this quote means is that when you promise something then you're going to keep that promise. Promises should never be broken. When you promise something is because your going to do it and keep that promise because you want that other person to trust you.  Once you break a promise you will lose it. You are giving your word. If you say you’re going to do something or keep a secret then you have to do it no matter what comes in the way of that. Although there are times when I break some promises but I didn’t think it was a big deal for me but it was sure a big deal for the person who was trusting me. There are times when you should NEVER break a promise when that promise is really sentimental or deep. But in general you should never break a promise if you’re giving your word for it.
