If we're travelling and our own house is many miles away, 'home' is wherever we're staying, together. If my hubby is one place, and I 'm at another place, I don't reach home until I'm wherever he is. He is my sanctuary.
I'm not saying he's a saint, neither am I, but no matter how mad we get at each other, in the end, there's always the comfort of his arms. There's this old cliché that says: He completes me. In this case, it's true. No matter how rotten a night I had at work, or how ill I was feeling, When I get home, I feel better. My house, my husband and my cat, is what home means to me.
Home is where I can go on the computer to write away the bad night at work, or the headache, or whatever. We've lived in the same house for going on 26 years, and we've put a lot of work into it. It's home.
