Not that kind of stars, but stars that use only a small amount of energy and in return they don’t shine particularly bright. Or for long. Same applies for the hearts I believe, and thumbs, for that matter. I wish there was a way to replace them, with something like a nod, but I guess that would be difficult to illustrate so that we all understood what it meant. Or—and I know I am being demanding here—words, even sentences.
No, better snap out of it. On we go. With stars and stuff.
