A promise of yes that does turn to no, is a sad and painful review. It runs through your mind, thoughts bad and unkind, self doubt displaces the truth.
You tend to accept your inner most faults instead of just looking toward pain. You beat yourself down, your head to the ground the feeling just drives you insane.
So if you give your word, a promise to one, prepare to make it come true . For if you turn sour, change your mind in the hour then you're painting the others world blue.
