You know, sometimes I type very phonetically. Not like trying to sound out words to spell them, but as I phrase my posts in my head, and my fingers follow along, they'll hit the wrong letter or type the wrong word. But it's obviously not a typo. I'm not typing "bacj" or "bavk", but "bad". Somewhere between my fingers listening to what I'm saying in my head and them actually typing it out, they misheard what I thought. It's kinda creepy to think about your fingers being a separate entity from your mind. And I wish they could hear better.
(the <del>word</del> worst one is typing h instead of y or vice versa. AYAYAYAYAYA for example. There was an afternoon a few years ago where I could not stop typing y instead of h.)
