We are in a team of 10, all women in our 20s and 30s. I have noticed 3-4 of them have become quite close and often do things together outside of work, go out for lunch when in the office without inviting others and have their own Teams chat etc.
I am generally quite mature and don’t get absorbed into office dynamics (I am friendly and open with everyone but I am not clicky or bestie with anyone either) but this has been bothering me a bit lately. I noticed that if only one of the group is in the office, they’d just go on lunch by themselves rather than asking me or someone else to join them, for example.
Some of these behaviours bring me back to school days, AIBU to be bothered by it?
