Modern life makes it very easy to know people lightly. You can have old school friends, work contacts, group chats, followers, neighbours, parents from school, people from church, people from the gym and still wonder who would actually notice if you went quiet.
People have layers of closeness
Research connected to Dunbar's social brain work suggests that relationships tend to sit in layers, from a tiny inner circle to wider circles of increasingly loose connection. That makes intuitive sense. You can recognise many people, but you cannot emotionally maintain everyone at the same depth.
This is why having a big network can still feel lonely. The issue is not the number of names in your phone. It is whether enough of those names sit close enough to carry meaning.
Social media can make the confusion worse
A feed gives you social information without necessarily giving you social nourishment. You can know that someone got promoted, had a baby, moved house, went to Lisbon and bought a new sofa without having any actual intimacy with them.
That half-connection can trick the mind. It looks like closeness, but it often does not give the body the safety of being genuinely known.
Adults need fewer better friendships, not infinite access
The goal is not to collect people like business cards. It is to have enough well-matched people close enough that life has witnesses.
A proper inner circle does not need to be huge. It needs to be real: people who understand your context, know your tone, remember your patterns and can tell when your fine is not fine.
