Why come back?

Over time there have been Flutheronians that have left, or been driven out, and returned, those who left not those driven away. My question is “why”? It would be like going back to an ex, chances are coming back after leaving would yield no better outcome or enjoyment than when one left, unless 70% of those who were here before the departure had also departed; highly unlikely. What would be the benefit of coming back here? Before you start splitting hairs on “benefit” just look at it as synonymous positive reason, or a plus to the returnee, etc.
