For me, being comfortable at anywhere no matter what it is would ideally be being at a place where every single person in that place is always nice and welcoming to me and would never make me feel annoyed/upset or uncomfortable with them at anytime. I know this kind of mindset is not that much of a great one since it is not realistic and unfortunately it doesn't exist at anywhere ever, but really if only everyone I've met meets those ideal expectations that I have then that would be the only time where I'd be comfortable and 100% willing enough to wanting to come to work/school/volunteer without ever feeling unhappy or feeling "un-present" on a single shift, nor having these kinds of thoughts I have that are ruminating in my head on the daily.
