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.
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”.
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
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.
