<human>: Can you condense the text into three sentences or less?

I was flying to Philly today, and I had a window seat. Upon reaching my seat I see that in the middle seat and the aisle seat are two sweet looking elders. I tell them I'm in the window seat, but the sweet old woman offers to move with her husband to the middle and window, giving me the aisle. I say yes, because I don't want to have to crawl over them and potentially hurt someone, so the husband moves over, but he's struggling a bit because he looked pretty fragile. As the wife was moving to the middle, the flight attendant came up and told me I could just sit in the seat behind the couple in the next row, and tells the wife that I'm going to do that. So the wife stops moving, I move back, and now the husband is sitting alone at the window, and the wife is sitting in the aisle with a seat between them. I watched them sit awkwardly away from eachother for the entire flight, not talking, and sitting in silence (they had been talking before I'd gotten there), and I felt like the most horrible human being for separating these sweet people.
