So are you all saying that the relative acceleration does depend on both objects, however, when we talk about free fall being independent of mass, as it is generally between Earth and an object with negligible mass it can be ignored?

We know that free fall acceleration is independent of mass.
9.8 m/s^2 on the Earth Surface
and
1.63 m/s^2 on the Surface of the Moon.
But what would happen if you dropped the Moon on the Earth or, the other way around, dropped the Earth on the Moon? Which acceleration would it be? Is...
