When a regular stops coming in, the whole restaurant staff notices. You matter in more places than you think.

You are in more people’s routines than you are aware of. The staff at a place you visit weekly, the bus driver, the neighbour who sees you leave at the same time: none of them are your friends and all of them would notice your absence, because regular presence builds a small shape in other people’s days without anybody discussing it.

If you are feeling unnoticeable, that is worth remembering rather than arguing with. It works outwards too, so say something to the person who serves you every week, by name if you know it. Regulars are easy to acknowledge and almost never get acknowledged.
