The Premise of a Promise

Actually.
What's the deal with promises? I mean, what is a promise anyway? "Promise". That's a word. That's all I get outta that. There are millions of others like it... Nothing special there.
But there has to be a bigger idea behind it all, right? Relationships are built and relationships are destroyed on the premise of a "promise". What makes that one word so powerful? I don't get it; seven letters - that's it.
I can seal any deal with a "yeah, I promise" just as easily as I can with a "yeah, sure". What's the difference? It's all just words coming out of holes in our heads, right? What makes that one coveted seven letter word so different from any other word? Different from any other phrase of confirmation?
I'm just saying: I think people make way to big a deal outta promises. I mean you break a promise to the right person - or maybe the wrong person - and it's the end of the world. Hell has frozen over, you are a big black demerit in their book of wonders, and you are OVER. Never to be trusted again. Nope, you blew it. YOU PROMISED!!
So what.
I try not to promise things anymore. No promises for me. Not because I can't keep one, or because I cannot stay true to my word, but because I think they're pointless. Instead of promising someone I'll bring the five bucks I owe them tomorrow, why can't I just say I will, and then do it? Why do I need to glitter and glam it up with a promise? Personally, I think the people who can follow through without having to promise they will can be better trusted than those who have to bond it with a promise so they'll actually do it.
Promises are ALL mental. They're for guilt and mind games, for two reasons:
a)So you can guilt yourself into following through with your word. It's a kind of self motivation; a source of initiative to actually do what you said you would. If you tell yourself your promised, I dont know... I guess that means you better do it. Or else!
b)So other people trust you. Even though, as I tried to explain earlier, people who make promises can't be trusted. Promises get broken allll the time. But if there's no promise...nothing can be broken...get what I'm saying?...
So basically, I'm an over-analyzer. Thinking things through and breaking them down until they pass the point of making sense is what I do. So take what you will, agree or disagree. No matter. Just my thoughts for the day...
