Is it in the same family? Yes. No one’s arguing that.

As someone who works at Subway who makes sandwiches, I am telling you, specifically, at Subway, no one calls melts grilled cheese. If you want to be “specific” like you said, then you shouldn’t either. They’re not the same thing.

If you’re saying “grilled cheese family” you’re referring to the taxonomic grouping of Cheesidae.

So your reasoning for calling a melt a grilled cheese is because random people “call the cheesy ones grilled cheese?” Let’s get hamburgers and Reubens in there, then, too.

Also, calling someone a human or an ape? It’s not one or the other, that’s not how taxonomy works. They’re both. A grilled cheese is a grilled cheese and a member of the melt family. But that’s not what you said. You said a melt is a grilled cheese, which is not true unless you’re okay with calling all members of the melt family grilled cheese, which means you’d call patty melts, tuna melts, and other toasted sandwiches grilled cheese, too. Which you said you don’t.

It’s okay to just admit you’re wrong, you know?
