I switch my letters. Like if I am going to write the word 'the', it would be hte. But like you I do it a lot. And I used to have a general spell check on my computer and now I do't have one or at least I don't know that I do. There are some words that I avoid using because I can't think of the spelling anymore where if I had spell check i would. Like the word 'unfortunately' I normally can't get. But I think this time I did!!!!!! Yeah. I think I need some ice cream to celebrate.
