There's a group chat you barely read that still includes you. Someone kept putting you on the invitation list for three years while you were busy. A colleague saves you the seat by the window without ever mentioning it.
Affection at this resolution doesn't feel like being loved. It feels like nothing at all, which is why surrounded can seem overstated on an ordinary Wednesday. The better test is what's actually there: the number of people who would notice if you went quiet for a week. That number is nearly always higher than the one you would guess.
