The one that got left behind

What comes to your mind when you read the title above? Make a quick list of a few things that do. It could be:
1. The ugly duckling
2. Some taste left behind in your mouth after having something utterly distasteful/pleasing
3. Some food speck left behind between your teeth
4. A good/bad memory, though more often than not, it's the latter that stays
5. The tune of some song that you just can't get out of your head
6. Some task on your list that you forgot to do

But, I ain't gonna to be talking about any of the above. What I'm going to focus my attention on today is on that last bit of poop left behind after you flush. No matter how hard your try, how many tumblers of water you put in, however fast, it just won't go down! It's like one of those resilient warriors; kind of reminds me of cockroaches. Every time you try a different angle to put the water in, and look in to see if you've managed to get rid of it, it just bobs up right back in your face. It's like as if it's there to stay. So, you try again, and again, and again, and before you know it, your bucket of water is over, and there's none left for you to wash your hiney!!!! You think "Now is a really bad time for me to run out of water". Reminds me of a few problems I've faced in my little life so far. They've mostly been self-created like this one, but more often than not, they just go away with time, or I find a solution if I think about it with a clear head; but not this one. No matter how much time you give it, it just stays there - probably soaking up more water, or doing whatever it does best. You know that the only way you are going to get rid of it is to flush again, or heave another full bucket of water in it, but you don't have the patience to wait till the flush tank is full again, and at the same time, don't want to waste another bucket of water, now that you've already used up one already. You start thinking and staring at that mass of excreta in a very contemplative way; but to no avail. Exasperated, you move on to let the next person clean up your shit.... Well, that's life....
