Let’s consider a two level energy system, one excited state and the other ground state. When a car is parked along side the curb it is said to be at the ground state, otherwise it will be on the road and belong to the exited state. Likewise, when the bikini is on in position it is at the excited state, else it is at ground state if the girl wears no bikini.
If you can tell me the blue car (in a transition state) is being leaving or parking you can tell me the transition is upward or downward. Same question, what do you think if the girl is de-dressing or pulling up her bikini? Not until you clarify the situation you cannot accuse our Seaman san hiding something from you.
Hoping my words is fair to both of you.
