You know what they say...

I was washing my face in the sink, thinking that John and I had once again managed to not get to bed early in spite of promising each other 3 to 5 times throughout the day that we would.  As the water splashed off my face and I looked into the mirror at my exhausted eyes, I thought "Welp.  The best laid plans, right?".  And then thought, wait...the best laid plans what?  I have used the phrase a thousand times but this is the first time it dawned on me.  What is the second half of the phrase?  Never work out?  And while sometimes good plans don't work out, indeed, it would seem that the "best" laid plans would not fall into that category a statistical majority of the time.  It is a truth wrapped up in a predicate-less subject.  Surely it started as a sentence.  The best laid plans go down in a roaring ball of flames?  No wonder it is hard to learn English.  It doesn't make sense why my head knows it means what it does.  I understand Bob, but the picture on the wall.  Yes, you stopped caring three sentences ago but the blog post on nothing.
