My sister and I live in a different country from the one we grew up in. She is single, I have a partner, and neither of us has children. At Christmas, she used to travel to the country we grew up in to spend the holiday with our relatives. However, for the last three years she has chosen to visit them at a different time of year and has instead spent Christmas with me and my partner. I think she now regards this as our new family tradition. The trouble is I don't want it to be. I find it physically and emotionally tiring.
For two of those years we lived in the same city. She doesn't have a car, so on Christmas Day my partner and I drove to pick her up in the morning, drove back to ours, hosted her all day, then drove her back home in the evening. We had no time to ourselves.
For one year we lived in different cities, so she took the train to us and stayed over from the day before Christmas Eve to the day after Boxing Day (at her request). Again, no time to ourselves.
My partner and I are about to move into a new home and would really like to spend our first Christmas in it on our own. We want to take things at our own pace and make our own traditions rather than spending all day (or several days) in host mode again.
My sister is mostly an easy-going guest, but she is vegetarian and we aren't, so we have to make sure there are veggie options, avoid roasting the potatoes in goose fat, etc. She is also quite a picky eater and will make it clear when she doesn't like something we've made her. My partner and I exchange Christmas stockings, and to prevent my sister feeling left out I've bought her a stocking and filled it with presents for the last few years so we can all unwrap things together.
She has always been very grateful for what we do for her and happily contributes to the costs, but the arrangement makes me feel less like a sibling and more like a parent. I'd like to take a year off, but if I tell my sister not to come she will almost certainly spend Christmas on her own. I feel guilty about this, but AIBU to want a break? And how do I tell her without hurting her feelings?
