This is one of those entries for posterity (the family journal). I'm going to outline a typical Saturday for our household.

The kids and their cute little faces greet the sunrise at 6:00am (5:55 lately) and drag an adult out of bed (usually Peter, bless his sainted soul). They eat/fling cold cereal, watch a few cartoons, and run around half-dressed (Calvin is into dressing and undressing these days).

We then wrestle, bribe, and sometimes brute force the kids into quasi-matching clothes and we all pile in the car. I drop Peter and the kids off at the library with a stroller, and then pick up at least 3 young women to cart over to a basketball game (I'm a coach) for two hours.
Meanwhile, afer abusing taxpayer dollars at the public library, Peter inc. catch a bus home, but it drops them off a mile away from our house, so he and Bryn walk/push Calvin in the stroller the rest of the way home. Bryn usually starts complaining about halfway through the walk, but we figure it's building character.

I come home a little later, we feed the children lunch, put Calvin down for a nap, set Bryn up with a computer game. I venture off for the local grocery store, MB, while Peter does homework. Saturday afternoon is perhaps the worst time to brave the crowded aisles of the MB, but I've gotten pretty good at negotiating tight corners and avoiding mean people and the deli area (plus, without kids I can go at pretty much lightspeed).
The coolest thing is that,
like Alicia, I have invested in mesh grocery bags and it makes me so happy to hand them to the bagger and not come home with landfulls of plastic bags. My one complaint is that the baggers never fill them to capacity. I'm convinced that I could more efficiently bag my own groceries, so ones of these times I'm just going to tell the bagger to move over and take a 5 minute break while I bag my own groceries.
Back at home, I try to bring as many groceries inside as possible (we have 27 stairs leading up to our front door, so I avoid extra trips). A friend of mine with six children told me she used to bring 6 gallons of milk in at a time (3 in each hand), which inspires me to attempt more and more items each time.
After bringing in the groceries, the kids mill around looking for the replenished snack stocks (this was also one of my favorite things to do as a child when my mom returned from the promised land of milk and honey- Macey's).
We eat an early dinner, hang out, or go out, or have friends over, and call it a day.
