For many a New Yorker, moving to the suburbs is more a compromise than a cause for joy, a decision that’s made all the more difficult by its grim finality—you’d often think moving trucks were crossing the River Styx rather than the Hudson—done with the understanding that a return to the city, if there ever is one, is at least 15 to 20 years in the future. But a small percentage of newly-minted suburbanites double back in a matter of months, desperate to return even if it means taking a loss on a house or squeezing back into a tiny rental again.
