Promises

They aren't meant for anything they are mearly words bonded by a special declartion this  is "I promise" it is an assurance and a chance all at the same time because no one is perfect therefore your promise is only as likely to happen as you make it.....promises are nothing more than expectations from one person to another person but just cause u expect it dosent mean it will happen this is the definiton by Promise: 
A declaration assuring that one will or will not do something; a vow
b. Something promised.
2. Indication of something favorable to come; expectation.... after looking at the direct meaning of it i feel like its pointless to make them just show it threw your action because promise is just that another word in the dictonary......
