You can either possess a cake or consume it. Consuming the pastry means you no longer have it.
I cannot believe I spent my whole life not grasping this phrase. Thank you. I’m embarrassed how much my mind just expanded.
There are a lot of clichés that may not make a lot of sense at face value. I’ve found some actually go a lot deeper than you expect, or may actually apply on multiple levels. Common wisdom often hits harder than I initially realized as I’ve gotten older…
Edit: and as you comment shows, I’ve also been guilty of straight-up misinterpreting the meanings as well. Literally just the other day i realized that Lifesavers™ candy are supposed to be little life preservers, as one would have on a boat. For whatever reason, i thought they were just making some grandiose claim as brands often like to do… Sometimes our first impressions become our impressions until correction which may not take place for a long time
I’ve only had this phrase explained to me recently, and since then I can’t help but think it would make more sense if it was told the other way around; such as “you can’t eat your cake and have it too”.
The problem is, that is the cake’s sole purpose. If it isn’t consumed it doesn’t mature and yield more cake. The analogy is a well known idiom, but it sounds a bit short when you think about it.
