We recently holidayed with long term friends. It was self catering for a week and a day in we realized that they weren't as much into cooking as us. This was ok with us and we continued to cook for all of us as it was quite an isolated location without much options. We asked for their opinion on the day's menu and hardly got any pushback. When they suggested changes we accepted except for - let's all have cereal for dinner. The food made was quite simple like pasta or rice and curry. However, as the week progressed their behaviour turned erratic. Sometimes they would shut themselves in their room and not come down for dinner with no explanation. We never asked either. Nothing else went wrong so it was strange. They would be fine otherwise too. Though this is the first self catering holiday together we have been on many holidays together and almost all planning like tickets etc. are done by us just like this holiday. We never had a problem with any of it as we like going with them. Were we being unreasonable? What could we have done differently.
