My life doesn't understand me

Is it just me or does everyone have days when every word you utter has been taken the wrong way? Days where no matter how much you smile and smooze, people look at you as if you've just driven over their prize winning topiary with a dump truck? Sometimes I feel that I am living one degree removed from society in a space that no one else understands. Yesterday was just like that. Even my guitar didn't understand me. I thought I was playing an Addagio in A minor, the guitar thought I was playing the theme from Camberwick Green.

Of course, "nobody understands me" is such a common complaint from teenagers and artist that the phrase is taken as a mantra to be trotted out, and ignored, at every opportunity. Usually this has an effect that lasts as long as a goldfish thought but if the artist happens to be a writer and nobody understands them then he/she is in big trouble....
