Both versions of this move — city to suburb, suburb to city — tend to be made for one reason and regretted for a different one. Space and schools drive the outward move; maintenance and isolation are what people mention afterward. Walkability and simplicity drive the inward move; square footage and noise are what they mention afterward.
Neither is a warning against moving. The point is that the deciding factor and the adjustment factor are usually not the same thing, and you can plan for the second one if you name it in advance.
