Office does not provide for social needs but provides a baseline level of social activity 5 days a week. I don't expect to make any friends in office but I am certain to talk to a few colleagues, have lunch in a group and make small talk every day of the week.

There is not much friction in all this since you know you are going to leave this behind at the end of the day. My interactions with close friends, although longer and much more meaningful, are also very bursty. The "mid-range socializing" (regular and frequent but not very serious) that office provides, that WFH is mostly unable to replicate in my experience, is something I am missing and I think it makes all the difference.
