Today is shopping day. When it comes time to go out, Ethel collects her cloth shopping bags from the closet and goes to the lobby where she waits with the other residents for the shopping bus. While waiting, they compare the latest news about their families, each boasting about their kids and grandkids in turn.
The bus comes and they leave the lobby, filing aboard the bus. The ride to the store is pretty quiet. Most riders just sit and review their shopping lists, though some talk to their seatmates. The bus pulls right up to the front of the store, which is marvelously convenient. They file out and the driver announces when he will pull back up front to leave. They all check their watches.
Ethel, having shopped at the same store for almost 20 years and also having fallen into a habit of buying mostly the same things every week, finishes her shopping quickly. She knows exactly how much she needs for a week and how much she can carry in her two bags without it being a burden. Since Ethel has twenty minutes before the bus comes back, she stops in the little coffee shop in the store -- a nice recent addition, she thinks -- and has a cup of tea while reading the book she keeps in her purse.
Five minutes before the bus is scheduled to leave, Ethel shuffles towards the front of the store. When the bus pulls up, she waits her turn and climbs aboard, setting the bags on the seat next to her. The bus never quite leaves on time; there are always a few stragglers and she is waits for them along with the driver and most of the other riders.
The bus drives back to the senior community, where Ethel gets off the bus and heads back to her apartment to put away the goods from shopping.
