When you are so completely exhausted that words blur together and you can't focus on anything. Yeah that is me right now. Luckily I don't look at what I am typing my fingers just kinda know when I am going to misspell a word...Gotta stay up so my ferrets can play for a little bit. Mean little toe bitters that they are... and at the moment I am typing with one hand with a garbage can in the other my little boy ferret keeps trying to crawl into the trash can
