I have noticed some dyslexics have a problem with punctuation and capitalization. If you read what they are actually trying to say it is obvious this person isn't stupid, although I am sure Grammar Nazis line up to accuse them of being dumb. Yes, yes this dyslexic knows the rules, but for some reason his fingers ignore them. And I think "thank God I don't have this particular problem."
...Or do I? Often when I proofread my stuff I will run across "a" instead of "I" as in "a went to the store" instead of "I went to the store." Huh? That makes no sense. Unless you read the "a" as "ah" as in "ah went to the store." Apparently I am not only failing to capitalize the personal pronoun but I am throwing in my Western accent to boot! Ha-ha! Does anyone else do this, or am I just "special."
