Home is the people around you
To me, home isn't the place we live, it's the people we live with like your mom or your dad or your brother or sister and even the animals that live with you make a place home. It isn't the roof above your head or the floor under your feet or the walls around you, or the couch under your bottom, it's the people you're there with. It doesn't matter if you live in a mansion or an apartment, as long as you have people you care about around you, it's home. Overall anything can be home as long as you have people around (or pets) that you care about.
