I go to the same cashier every Tuesday. Yesterday was Yolanda's "Friday," and she was very excited for the "weekend." She asked me how my camping trip went. She was going to have tacos for dinner.
If you choose to value relationships with the people around you then the world doesn't have to have changed very much at all.
Yeah, but there are many ways to achieve this without the grocery store. There's nothing special about it as an irreplaceable social hub.
My point is, compared to going to the butcher and baker, who are artisans running businesses that are to some extent expressions of theirselves and maybe even their heritage, a supermarket is relatively soulless.
Save the time and do something like dance, art, or sports.
