Oh, please. People who have never left their home in their entire life probably wouldn't. Why would someone who stopped leaving their house lose their favorite? I haven't lived in my hometown in 20 years, but I still have a favorite park from there. My vegan friend once said she misses lobster. Someone who lost their hearing could still have a favorite song.

Just because life circumstances change, doesn't mean they have no memory of how things used to be.
