As a background, I am currently working as a foreigner where in 90% of my colleagues speak the local language and while the other 10% speak another language. Cut the story short, I'm the only one in the office that is of my nationality.
We recently shifted office and my seating arrangement changed.
I am currently sitting in the middle of a group of all-locals and they'd often speak their language unless they're specifically speaking to me (where in they'd switch to English).
For one, I am not complaining that they should speak in English. It's their country and they can speak their local language.
However, I feel very distracted and feel unintentionally left out when they banter which I didn't feel when I was seated further. It makes me very unhappy in an otherwise friendly and nice environment.
Is it reasonable for me to ask one of my colleagues, who was actually was previously in the same seating position I currently am to swap seats? I say same position because the arrangement of the group didn't change even if we shifted office. Only the two of us swapped. His seat is on the edge and I'd feel more comfortable to be a little bit further from the rest (which was where my old seat was).
I don't know how to say it to him without offending anyone. Like, what if my current seat mate thinks I don't like him (which isn't true) because I wanted to change seat. And without coming off as fussy. But it really affects my concentration.
