I checked something off the list today

I always have a million "to do list"s lurking. Multiples because it seems that I lose them as soon as I finish writing them. I can list my lists:
grocery list: divided into three parts, always stuck to the side of the fridge. It has the "Costco" list on top, then things that I need to pick up when I'm out doing errands, and the real grocery list on the bottom. It's on the bottom so that I can rip if off when I leave the house, and still have the other lists where I can find them.
house repair list: this one is just a dream list. Everything that's broken, worn out, or just somehow icky. Nothing ever gets crossed off this one. Or maybe, once or twice a year something gets done. But then it usually gets back on the list because I did it wrong. Like grouting the showers. Check. Then, after a few weeks, it''s back on the list. I'm a lousy handyman.
reading list: books get on the list, then when I find them and take a look inside, they usually go back on the shelf. But if I don't try to insist on high quality (or "guilty pleasures"), then I do find a few. A couple of weeks ago I read "The Broker" by John Grisham, and "The Other Boleyn Girl" by Phyllipa Gregory, and liked both of them.
the "don't forget this" list: this is the stuff I write on sticky notes and post on the front of the kitchen cupboard. It usually works! People I need to call, people I need to remind Alan to call, pick someone up, or pay for something. The important stuff - I put it right in my face.
the real to-do list: these are the lists that are scattered throughout my life. People to call or email on my desk. Lists of things I need to do pick up for the next Ward activity in my purse or clipped to a file folder. The list of things that I need to buy or pack for Heather to take to college is tucked between the bath towels that I packed into a shopping bag. I know where to find this list! The lists of things I remember just before I go to bed flitter around my nightstand and disappear into the drawer, under the bed, or, rarely, find their way into my purse. Or, the best one - whatever is really important is scribbled on whatever scrap of paper I can find, and then gets lost in my purse.
Yes, I am a list maker. And the things that are really important usually get taken care of. But if they're not of earth-shaking importance, they're really just giant confetti.
Today I checked off something that never even made it onto a physical list, it was only an item low on a mental list: changing out the brass knobs on the kitchen cupboards. But I was at Target, and saw some great knbos for a great price, and how could I resist? Unfortunately I was two knobs short. Because I didn't count the doors and drawers before I left. Because new knobs were not on a list. So the cupboard above the fridge still has brass knobs because who ever remembers that there's a cupboard up there? That's where everyone keeps the stuff they never use: ice cube trays, ugly candles (for if the power goes out), the blow torch for making creme brulee, and thermoses. And that's why I forgot it. The forgotten stuff in the forgotten cupboard.
So, what I need to do is write "two more knobs" on a sticky note and put it on the kitchen cupboard.
