My wife and I have been married for 4 months. We were visiting family back in our native country and this was our first long-haul (14 hours) flight together (our honeymoon had been an hour long flight). To give some context, I work in the morning and have a consultancy firm too, and my weekdays, and some weekends are super busy. These flights have always been the rare times where theres nothing I can productively do, and so I just look out the window or read some Sherlock Holmes. My wife and I chatted during the initial hour but then I fell into my routine of reading and looking out. Whenever my wife talked about the events we'll be attending here, the people we're seeing, I would definitely engage, but admittedly I wouldn't be putting too much effort into the conversation. And my wife didnt talk much either after a few hours (which I now realize was her being pissed off). When we were at the carousel and I made a joke about a strangely shaped suitcase, she said "you want to talk now?" and told me how rude I'd been during our flight. It was news to me and I said I was just trying to follow my regular routine but she was still in a bad mood. She's good now, but she did say that she'd thought our first long flight together would be a certain way and I'd disappointed her. We have a flight of the same length back at the end of our 2 weeks, so I wanted to ask if I was TA here or my wife was the one being unreasonable?
