I wouldn't say mine is a "sick to my stomach" feeling. To me this feels more like when bread pops out of the toaster and you open the jar of peanut butter only to find it's almost gone and there's really not enough to spread generously over 2 pieces. There's no good alternative like jam, because someone in the house likes orange marmalade not strawberry like normal people and you didn't do the shoppin, or even worse, regular buttered toast because the butter is still cold in the package in the fridge and everyone knows that butter straight from the fridge (even cut into the thinnest of pats and placed in orderly rows between 2 slices of warm toast to melt) never really melts all the way and wind up as uneven butter blobs because it wasn't really spread like it was meant to be in the first place. Besides, the whole project was begun to meet a sudden craving of PEANUT butter toast.
So rather than settle for an alternative, you do an eyeball-estimate of peanut butter left in the jar, factor-in the difficulty you know will come, and spread just enough onto the first slice to meet the minimum threshold for satisfaction. Then you extract the last easy-to-get-at blobs and spread them on the 2nd. As expected, the 2nd slice is so woefully under-covered that to stop there you may as well have put more on the 1st slice and eat 2nd dry, but you knew this already. You knew this would happen when you did your initial estimate and still committed to 2 slices of peanut butter toast, so you get to work making it happen...scraping scraping scraping spreading scraping scraping scraping spreading....undeterred, spreading meager bits of peanut butter thinking "I WILL get at every bit!". You're rewarded with noticable progress at first, but your 2nd slice is still unsatisfactory when you reach the point...and everyone knows the point I'm talking about... where the amount of peanut butter removed per scrape dramatically plummets...
Now it's gut check time. The moment of Truth to see what kind of person you are. If you want to make any more progress with the dwindling streaks you'll have to apply more and more pressure as you scrape and dig around in there, but you're know that because you grabbed a regular table knife (way back when you thought there was plenty inside the jar) and they have those those teeny tiny serrations on the part of the edge you're using, you'll also be carving-out an increasing number of little curly-tails of peanut butter jar plastic from the inside wall as you do, and they will wind up on your toast.
Not being metrosexual enough to have bought an array of rubber smooth-bladed spatulas in order to have one small enough to get into the jar and extract the PB efficiently and cleanly, or to know where they are if your wife had snuck some into the house, and even if she had and you knew where they were around there somewhere, are you so gutless as to actually put down the knife and rummage around for it? Rummage around for a limp rubber and plastic handled spatula, something that is used to put icing on cupcakes?...
Hell no. Even with nobody looking it's already lame enough you're handling a knife that has no killing point or heft and edge that could cleave a skull or gut an elk, but at least it's a metal knife, kind of. Hopefully, you're not even aware of the spatula-option because your mind is tweaked to shoot it down prior to it even becoming a blip at the edge of your gray matter radar display. No, the most you maaaaaybe register in your mind is "Sure, if I continue to scrape harder I'll be ingesting some plastic petrochemicals", but even as you do you dig-in without outwardly missing a beat. That's right, you dig-in hard, then even harder as you embrace the notion that you have the kind of intestinal fortitude that will shrug off anything passing through your system...hundreds perhaps thousands of petrochemical solid curlytail scrapings...so what. PCBs, dioxins...whatever. A noxious cocktail sludging through your guts....you know you can handle with not so much as a blink. You want peanut butter toast and don't care what else is on there as long as the peanut butter is.
And so you scrape every bit of contaminated peanut butter out of the jar and now you have enough for the toast. And you eat it. And you like it. And it tastes extra-good...maybe even the best you ever had.. because you threw away the scraped-clean peanut butter jar deliberately into the regular garbage bin, not the recycling bin where the kind of people who would have gone for the spatula would pester you to throw it, and didn't settle for inferior orange marmalade or that goddammed cold butter either.
That's more like how I feel right now.
