I have only ever lived in two other places my whole life, both of them on the same site, one of them the caravan when I was born and then when the bungalow was built that was it. It's getting used to the stairs as I've always lived on a single level, getting used to the cabinet in the kitchen that you have to open & close the doors in a certain order, having carpet in my bedroom rather than laminate, showering in a cubicle rather than a bath. And they are all so little that you wouldn't even think you would notice them. I still have all the same bedroom furniture, the same ornaments and trinkets and yet they look so different. And those little things do matter
When people ask how it is I don't know what to say. I say amazing, great, fun, strange, quiet... and it's all those things and more. There are so many things about living with someone who aren't your family that I hadn't even considered before. My room mate is one of my best friends so to be honest in some ways it is probably easier than a stranger because we know each other. She knows that I am fussy about food and get moody after a long day at work. But then we also have more to lose, you can't fall out over things like who last washed up or stupid inconsequential things like that because what is that in comparison to a friendship.
Also to note that on the practical side of things I kind of didn't follow my own advice. I took no pictures - just bundled everything in - still haven't taken a picture in this place! And I just crawled into an unmade bed that has some clothes I need to put away on the end of it! Do as I say people not as I do.
