Normal reflections are a tiny bit dimmer than the thing they’re reflecting, no matter how shiny the surface. They can’t reflect light 100% perfectly, so even if a little tiny bit is lost each time, the reflections will eventually end. That’s why fun-house mirror halls don’t truly go on forever and seem to darken in the distance.
Love need not be like this. You can reflect it a little brighter than what shines on you.
