Living alone as I do out here in the back-of-beyond, it's necessary to plan ahead. The cupboards are stocked with a second, backup staple so I don't get caught without. Whenever I open a jar, can, bottle, box, or bag of something, that something immediately goes on the shopping list (a dry-erase board on the refrigerator). When the stores are miles away or close at dark, it doesn't pay to run out of anything. Case in point, I found out yesterday that Clay is coming up later this morning. Bread doesn't keep well and I don't use much anyway, but it did seem ungracious to have to ask him to bring a loaf so I can make him some lunch. I am out.
On property as large as this, it pays to pre-think every project. It isn't as if you can holler out, "Honey, bring me a thingamabob, doohickey, whatchamacallit, or widget!" I logged many miles as Steve's gopher (go-fer) when he'd send me back down to the shop or the barn for some forgotten tool. I may load up with more screwdrivers or wrenches than necessary, but that's better than having to stop mid-project to get another size.
Probably the most important thing to remember is to put a fresh roll of toilet paper nearby when the one in use is getting low.
