Sitting in a Middle Seat Between a Couple

I took a last minute flight and got put in a middle seat. No one’s favorite. But a few minutes after boarding it becomes clear the people I’m between are a married couple.

I selflessly offer to let them sit by each other, but they say “no chance”.

At first I’m a little bugged, mostly at getting the middle, but as they talk over me during the flight and exchange times over me (snacks hand sanitizer, etc)… I grow to respect the move. I’ve always chose to sit my my husband, thinking it was a reflection of our relationship - but I’m loving the idea that this couple is comfortable enough in their relationship to recognize the middle seat sucks.
