88%* of the time I am very socially awkward in person for a long time until I warm up. You might think I have a little Asperger's, but that's not quite true, at least I don't think it is. You might also think I'm rude because I'm only sporadically talkative, but I'm not really being rude - I'm just a little ratarded. Fortunately, I spend about 34%* of the time at work communicating through machines, 25%* of the time in some stage of sleep, so that leaves just 29%* of the time for me to be socially awkward. What's the other 12%* of the time like? I'm not really sure.
*approximation, based on what I think might be true.
