6/ The work friendships that survive everything are rare and worth keeping.
The ones that move from office to real life.
The ones that make phone calls that have nothing to do with work.
The ones where neither of you needs anything from the other except the actual company. Hold those ones carefully.
2/ The colleague who sits next to you every day is not automatically your friend. They are your proximity.
Proximity feels like friendship because you share space, complaints, and eye rolls at the same meetings.
But shared suffering is not the same as genuine connection.
