My hands suffer from digital Alzheimer's. Although my brain might know perfectly well how to spell a word my fingers have a mind of their own and I refuse to take responsibility for any errors at all.
I can't think of any specific word I misspell regularly. There must be some, I'm sure.
My first name always gives me a problem.
About a year ago someone called me "conceited" and it wasn't a word I was familiar with so I rambled at someone for about an hour complaining that someone had called me conceded. I was finally corrected though ;) also I mess up too and to allot. I do know the difference but I type to fast and always like to add the extra "o" then I feel the need to correct myself. Also my phone always changes definitely to defiantly. BAD PHONE !! ;)

I just learned how to spell "tomorrow" right every time, lol.
