It might be true, but that's no way to treat a person you love or care about. You are your phases. The present is the only time that really matters. If you aren't going to accept who they are now, you don't accept them.
When any current moment is over, it immediately begins to lose all shape and color. Like a fish pulled out of water and left to die on land, its colors pale and it flops helplessly around until its life energy ebbs beyond a certain point and it dies. However, there are some moments that refuse to die. As they weaken, they stumble and lurch through the now, wreaking havoc. Colliding with lives and events, they leave their mark, aroma, their scales, on everything they touch.
