That's a personal 'quirk' of mine. When I'm happy, I usually type in lowcaps. Also, I've seen worse, but I think my personal reaction at the time had something to with the fact that my skin condition was playing up. I think I posted about that in the WHIYL thread at some point, but I don't remember if I elaborated on that or not.
Basically, bad enough temperature/weather = I literally get so itchy that I cannot accomplish anything. It's controllable, though. It's actually improved even, later.
But yeah, I was itching like hell earlier, and I'm a bit paranoid about my skin thing. I'm going to spare showing you some of the worst stuff I've seen unless you pester me into it, though. Bad **** I've seen is pretty annoying like that; While I can make myself forget it, it pops up every now and then.
Typing this out felt really...weird. Like the tone of it and stuff. Ugh.
