Eli5 is there no such thing as cold?

My SO said the above statement and gave me an explanation “Cold is the absence of heat or energy”, it does make sense however in my head it is like saying (in very simplistic terms) “the countryside is the absence of a city” and that is just a ridiculous statement.

Cold does exist as a concept. Cold things have a lack of heat. Physics nerds still talk about “supercooled” things. So despite what science teachers tell you at school, scientists aren’t pedantic weirdos who deny the existence of cold as a real life concept.

Cold doesn’t exist per se, but only in the same way you could say that poor doesn’t exist.

But obviously poor does exist. Most of the world is desperately poor. It’s just that there is no physical thing called poor, poor is a lack of riches.

Heat is energy, cold is a lack of energy. But it’s still perfectly OK to say “close the window, you’re letting the cold air in.” You don’t have to worry about the physics nerds telling you off, because you’re dealing with real life.
