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.

People are getting it a bit backwards, cold is not the absence of heat, it is the absorption of energy from the surrounding area into an object, that’s what makes it feel cold. Heat is the opposite were it is giving of energy into the surrounding environment.

If you had the absence of heat the object would not be cold but neutral to the temperature of the surrounding environment, to feel cold it must be drawing/absorbing energy because that is what we perceive as cold
