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 is a real, meaningful and useful concept in daily life.

Cold is not a concept in physics. There is no way to measure or even define “cold.” It is only correct to say that there is no such thing as cold in the context of physics.

This is limited to one domain of science – physics. For example, in biology, cold is a useful concept.

Your SO is correct if you were talking about physics and incorrect in any other context.
