Home’s more the feel of a place than an emotional attachment for me. Never lived where my folks live now, but always notice how much more homely it feels than my own place (or most people my age, maybe it’s a generational thing?) - always warm, smells of cooking, comfier.
In a way i think it’s a good thing that parents move. Imagine the emotional wrench of having to deal with selling a house years down the line where you have decades and decades of memories, right from childhood to your parents being old and passing on. Could be very tough.
