Okay, I know many people would tell me it's a correct term. But I kinda just draw my reaction to a theme if I can't think of a nice interpretation. I don't know what to draw except for cliched bits of glass. But then "broken pieces" sounds to me like someone took the pieces of something, which implies it's broken already, and broke them… more. It's like "frozen ice" or "generous altruist". I dunno… It's tough for me, I don't get many puns, I can't write my own, I can't be sure if my text is correct unless it's very simple. In Globish, as someone I know would say. Always expecting some rotten tomatoes because of that.
