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.

Eli5: I’m from Florida, where its very hot. My friend is from Alaska, where its often very cold. Today it’s 60° out, and it feels a little chilly to me, but my friend says its still warm.

Heat is a discretely measurable property. You can’t measure cold with a thermometer. But this is true of many things. You can measure caloric intake, but you can’t measure hunger or fullness. You can measure hours of sleep, you can’t measure tiredness.
