What makes it feel home?

It is hard to believe that only 5 years made Princeton feel like home more than anywhere else!  Even more hard to believe what a simple thing like COSTCO can bring the feeling of home back.  We visited the Indy suburb Costco over the weekend and felt like being in NJ again!  Thank for the standardization and commercialization!  but truly, Princeton feels home for me because of the friends there, the casual phone calls I can make to Danchen, the random coffee breaks i take on a work day with Latrice and Danchen, an unexpected dinner-together on Friday evening just for sake of getting together......  For Easton though, Bloomington becomes his home even before he moved down here, because "Dad is in Bloomington!" (in his words).
