Life can bring all kinds of promises. Find a way to make the best of that promise. Having a moment to just let it be kept as long as possible.
Something can bring so many promises in such a sense. One of those things is happiness. Happiness can give its promise of this sense of confidence. Find it a bit different from anything else.
It is entirely understandable to remember one promise. As if someone believed in anything. Putting that bit of expression when it comes to keeping promises. Letting themselves feel honest to keep it to themselves.
