What makes you feel at home?

I know of 2 places that truly felt like home to me, one I want to return to one day, if possible, the other only exist in my memory.

I know when I have helped people move they can even start to cry as they are leaving their home after many years and say their goodbye and I have not said anything but try to show compassion. To me it is a blur of all the places I've lived except for those 2. To me it is not the years, that much I have gathered that make me feel at home or not.

It would be interesting to know how others feel, what is it you think that makes you feel at home? Why do you get attached to one place but not the other? And so on. Anything you wish to share :)
