“I want my cake and eat it too/also”.
Cake is perishable, so if you have your cake, rejoice. Eat your cake, leaves nothing.
If, it isn’t gone already? Should someone else find it!
While the fantasy sounds good, it is fleeting.
But if you come close, remember; “Don’t bite the hand that feeds you!”.
Cake and Eat it too
When a person mistakenly wishes and uses this to get both or all of what they want. When used negatively to express the impossibility is better usage.
