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.

Basically it depends on if you’re talking to normal people or to Physicists.
If you are talking to normal people, cold is a thing. Things can be cold, get colder, and cold can “spread” if you stick ice to something.
If you are talking to a Physicist, cold is the absence of heat. Things do not “get cold” because that is just them “losing heat”. Things are not “cold” they just have “a smaller amount of heat”. Cold does not spread, that is heat leaving the thing you stuck the ice to and entering the ice, melting it into water.
We can’t always be 100% correct like that or things get too cumbersome. It’d be like if I told you a car is going 60mph, but you corrected me and said, “Nope! You forgot to account for the Earth’s rotational velocity, orbital velocity, and how even our solar system and The Milky Way are constantly moving throughout the universe. That car is moving way faster than the speed of sound!”
Too many incidents like that and people stop inviting you to parties.
