The zeroth law of thermodynamics states that if two thermodynamic
systems are each in thermal equilibrium with a third, then they are in
thermal equilibrium with each other. Accordingly, thermal equilibrium
between systems is a transitive relation.
The fact that temperature obeys a transitive property is by no means intuitive!

The city closest to city A is B, the city closest to B is C, but A is not always the closest to C
