On a recent flight, my partner was three rows in front of me as we weren't too bothered about paying to sit together on a 2-hour flight. After we got on, he brought me a sandwich from his bag. The woman next to me realised we knew each other and offered to swap to his row to sit next to her relative. I thought, "Great," but he immediately said, "I'm very sorry, but I'm settled where I am." To be honest, I was taken aback, as he'd only been on the plane two minutes. He made some excuse about how he put his case in the overhead locker, but I said it didn't matter as he could still move. He glowered at me and gave me such a look I was fuming. He had no real reason not to move. Am I being unreasonable to be put out about this? It just struck me as a really weird thing to do.
