Do you talk to yourself? Do you hum to yourself? Do you sing to yourself? I do all three, occasionally. I am not embarrassed by it and nor do I reckon I'm a mental case for doing so. I'm pretty observant, I know for a fact I have seen people in cars with their music on loud, alone, singing like X Factor auditionees. Properly immersed in their time with themselves. I happened to be going down the motorway, with my Dad, a week or two ago, when I noticed somebody doing just this. A middle aged man, he stopped singing immediately once he realised he'd been noticed. I felt as horrid as he did. I felt a bit rotten for stopping himself enjoy his journey. I continued to look out for other driving singers. There were many. I can only assume it is a common thing to hum and sing, and even talk to yourself. However, there are a few things I wish to ask and draw from this observation: 1) How come people feel embarrassed about it if caught out. Whenever I've done it, it's always seemed quite childishly fun. So why does the feeling of being a complete nutter arise when you are caught doing it. -- I also mean, being caught by yourself. i.e. you snap from your humming trance, and realise what you've been doing??? honestly, I have felt like I'm an absolute grade A-1-A loon before, even though I know I am not. 2) Is it possible to type out humming? The pronunciation of each little notelet of hummingness, to produce a series of nonsense words that if hummed as shown will produce a tune? Doo--da---do-do-do-----Doo-da-do---Doo-Do-Dah-Do-Dah-Do-Do--- (Part of the Scooby Doo theme tune, my favourite theme tune to hum btw). 3) What sort of stuff do you sing, or talk to yourself about if you do this? I'm putting my head on the block here. Everyone might think I'm crackers. Any thoughts.
