"Home"

My dad was in the Navy, so growing up "home" was a new house every year or two, strung together with a new bedroom and new school.  My freshman year of college, I fell in love with what I thought was a deep and profound statement (aka described exactly how I was feeling transitioning into college) about "home" from a quote Andrew (Zach Braff) describes to Sam (Natalie Portman) in the movie Garden State:

"You know that point in your life when you realize the house you grew up in isn't really your home anymore? All of a sudden even though you have some place where you put your shit, that idea of home is gone." [...] "You'll see one day when you move out it just sort of happens one day and it's gone. You feel like you can never get it back. It's like you feel homesick for a place that doesn't even exist. Maybe it's like this rite of passage, you know. You won't ever have this feeling again until you create a new idea of home for yourself, you know, for your kids, for the family you start, it's like a cycle or something. I don't know, but I miss the idea of it, you know. Maybe that's all family really is. A group of people that miss the same imaginary place." 

Is home where you physically live?

Is it where you feel you belong?

Is it just a memory, or a feeling of some sort?

Almost 25 years later, I still slightly confuse myself when I tell someone "I'm at home" or "I'm going home."  Most believe I'm referring to the apartment I now live in, and most times, I am, but there are the glimpses of my family home that flutter across as I say the word "home".

What do you consider "home?"
