Sit with them. Get to know them. Discover an interest they have. Connect them to other people who share that interest. That would basically mean I would be a middle man in between
Other idea I have is to incentivise people sitting alone to approach other people sitting alone, which is a more passive way of doing things
It’s one thing to eat alone, and it’s another thing to eat alone while wanting to eat with people but not being able to for whatever reason(Loneliness). I’ve felt that and it’s not a nice feeling.
