"That's neither here nor there."

One I've never understood is: "you can't have your cake and eat it too."

Not only is it possible to have your cake and also eat it, it would seem necessary to the act of eating the cake that one also possess it.

I've read a few "explanations" of this online, but I'll wait to see what others might say before I post any.

I have a cake.

I want to eat my cake, but then still have it.

But if I eat it, it will be gone, so I won't still have it.

Hence I can't have my cake and eat it too.

Think "I want to spend my money but then also have money in the bank".

Then the phrase should be "you can't save your cake for later and also eat it now."

Unless you don't eat all of it now but rather only a portion.

Being a Philosophy major, I actually see a lot of validity and meaning in phrases like "It is what it is."

defend yourself, then.

There's a 50/50 chance it could go either way.
