Don,

While it may be difficult for normal people, for others with dyslexia it is truly troubling. A few of my great hurdles were weather/whether, dessert/desert, through, thorough, threw, warehouse/wherehouse. But alas, I overcame and years ago passed a test on words and meanings and received the highest score of anyone they ever tested. That was nice. I guess that is one of the reasons I get upset about abstracts in a single paragraph.
