Thermal Equilibrium with some humour

The other day, I was asked by a student to explain thermal equilibrium. I told her to guess an answer. So she said that thermal equilibrium between two bodies means they are at equal temperature and there is no flow of heat between the two.
I said, “you got the first part correct and second part wrong. There is equal heat exchange between the two bodies”
I added, “the electrons carry heat and the amount kind of depends on the body’s temperature.”
She asked, “if the other body is at the same temperature then why would the electron carry heat there?”
I answered, ” it is because electrons don’t have phones.”
