Is it normal that i cant stand it when promises are brocken?

I keep all my promises and I'm very careful which promises I make...so I expect the same from the next person, especially when I work on a project with someone and if they don't deliver as promised, I can really make them miserable.

I will always do as I promise if humanly possible. If I cannot, I will call, or find some way to let them know I cannot keep my word at that time, and do whatever I can to make up for it. I go ape shit when someone agrees to do something or call at a certain time, and fails to do so.
It takes so little effort to call and say you'll be late, something's come up or whatever. I can not forgive a person who just can't be bothered to keep their word or at least communicate, and they will probably never be able to earn my trust back. Life is too short to bother with inconsiderate people.

Some promises are made to be broken. It depends on the person who is making the promise. I make people "fuck swear" on certain promises. A fuck swear is when you intertwine the middle fingers as well as the pinky. It is more classy and you should give it a try. ;)

It depends. Like, some promises are made on an informal short notice. They get broken, made up later, maybe. No big deal. If a biggie promise gets broken? IMO, scratch that person off your list of friends. That one is unreliable unless they have an explanation you find acceptable. If you want, insist that everyone make promises as an obligated contract in writing. LOL! I'm joking (sort of).

I prefer not to make many promises.

I only make promises that I have chosen of my own free will. When someone tries to pressure me into making promises to do them favors or change something about myself I say no, but there was a time when it was much harder for me. If there's one thing I hate it's a persuasive person with an agenda!

When I make a promise I keep it, but my sister is the kinda person who tries to bully people into making the sort of promises she wants to hear. She tends to try force people into making stupid promises to her, and a lot of people just say yes to shut her up then she's surprised when the so called promises are broken.

My sister was quite verbally, emotionally and even physically abusive towards ex fiancée. When he left her he told her he was going out of town on business then she didn't hear from him for ten days. When he finally called it was to break up with her. There's so much more drama and dysfunction to this story, but I'll spare ya'll. Anyway, my point is that he broke a promise that he needed to in order to take care of himself and get out of a codependent and abusive relationship. Sometimes promises need to be broken for the sake of our own self preservation.

No I hate that too. Im the kind of person who says they will or wont do something then I stick to it.

Now sometimes life happens and your not able to fulfill your word...and thats understandable. I have had things happen before.
But a lot of the time people break their promises because they dont feel like doing whatever it is...and thats shitty
