The cooking I refer to is more the baking when she was younger. We don't bake day to day, so baking buns and cakes was a treat for holidays or special occasions.
Due to time pressures elsewhere I do the normal day to day cooking during the week and we are normally (pre covid anyway) out eating at weekends or have visitors. I don't mean that type of cooking. DD likes to invite a group of mates over and they cook a big 3 course meal together, for example.
DD is 18y now but has always been very sociable. She loves spending time with her friends and her family. She'd much rather be out and about with friends or visiting family and having day trips to places than being stuck in the house doing school work.
So she'd do things like catch the train to visit my sister and nephew and enjoy some time with them, helping to entertain her young cousin - or visit my parents (also 2-3 hours away) and have a day out, a meal and stay with them for a day or two. She'll visit local attractions with her friends or o out for lunch.
I don't understand how you'd get bored with spending time doing a variety of things over a few weeks (normally only 4 as we have a family holiday for 2 of them) such as spending time with loved ones, reading, or watching a bit of TV, visiting different cities, going for a walk with mates, having meals out, going to the cinema, bowling, skating, etc.
Why do you do in your holidays, besides work, if not doing those kind of activities?
