Fruitcake and wingnuts

What do these two have in common, besides sometimes being used as derogatory terms for people?  Well, I shall tell you (I know you have an inquiring mind).  On the surface they don't appear to have anything in common.  After all, a fruit cake is made up of fruit, sometimes booze, and flour, all mixed together and left for a very long time to "age".  One of two things can happen to a fruitcake.  It can either be too moist and thus become quite heavy to eat, or too dry and difficult to eat.  If it's too moist, you can at least swallow it in politeness to your host/ess.  If it's too dry it makes faking your way through one piece hard enough, only to have said host/ess press you to have more (s/he doesn't want it so she/he will foist it on you).  You can always play the polite guest game and either take a second piece (that you'd really rather not because it's like eating sawdust and has the same consistency as a McDonald's burger) or you can beg off saying something along the lines of how you just ate dinner and are much too full to be able to eat any more, or you are on your way to lunch/dinner/supper and don't want to spoil your appitite.  Either way you need a way to get out of the situation.  Which leads us to wingnuts.  You know the kind that are supposed to be easy to put on a screw in order to hold something together.  That works fine, if the wingnut in questions works well with the screw, but of course it doesn't always.  Instead the wingnut either won't screw on properly because the screw is too big (even if it does come as part of a kit), or you get the said nut on the screw only to find that not only does it go on easily, it mostly spins in one place and doesn't hold anything together.  Are you following this so far?  Good.  Now we come to the connection.  The dry cake is much like the wingnut you can't get to screw on.  No matter how much you try, it just isn't working for you.  The moist cake is much like the wingnut that spins in place but goes no where.  There is just no way to make it work, and it usually falls apart before you can get it to do anything you really want it to, thus leaving you less than satisified, and often with a mess on your hands that can't be patched up no matter how hard you try to put a good spin on it - so to speak.  Why should you care about all of this?  I have no idea.  It was just one of those random thoughts that meandered through my mind when I was doing something completely unrelated.  As usual.  Until next time.
