I've never been much attached to houses and furniture/possessions. It's probably my nomadic heritage kicking in there. Also, we have moved dozens of times throughout my childhood and adulthood. I do become extremely attached to people though. I find it difficult to imagine living in one home for the rest of my life, maybe it will happen, who knows! As long as each home/neighbourhood is an improvement, I'm ready to move without too much heartache.
I do think I have grown attached to this city in general though... if I am away for more than a week, I get terribly home-sick, I've developed a lot of habits, tastes, and routines, that I find difficult to go too long without. In fact, I haven't left it for four years, the first three through choice (I missed the summer feeling we have here while I was away), and now through lack of opportunity. I don't mind too much though. I'm content, all thanks to God.
As to furnishings, I do have my own tastes (I like Regency era furnishings and deco, I've probably read too many period romance novels

), but haven't had much opportunity to go to town with them, I often give free reign to loved ones, as I am usually more flexible about these things and adapt quite quickly to different tastes. If that's what keeps another soul happy, I am ready to oblige. I do speak when something is just too horrendous to live with, but haven't found much opportunity to say so. Thankfully, I've never lived with someone with a penchant for safari orange, leopard print or other such eye sores.
Whenever I think of home, I think of my grandmother.
