For me, discomfort due to poor English, slang, misspelling and mispronunciation cause real distress. I don't believe it is any different from the stress those of you with AS experience with uncomfortable clothes. I can't prevent myself from reacting with a flinch when I notice any mistake. Every grammar, punctuation and pronunciation lesson that was ever taught to me in school is like a decree from God. However, I remain a terrible speller. I never send anything without using a spell checker. I think my poor spelling may be due to being taught to read phonetically. With the "see, say, hear" method of teaching reading the reader recognizes the "look" of the word. These people often don't do well with multisyllabic words that are unfamiliar to them. I am very seldom corrected regarding my use of English and when I do make a mistake, I am grateful to have that error pointed out to me, as long as it is done gently. My agonizing need for perfection in language is definitely one of my many very uncomfortable AS traits. It is inconceivable to me that, once an error is pointed out to a speaker/writer, that person doesn't immediately make every effort to become correct. I do wonder if the quality of teaching in the US may have declined since I was in school (I was born in '44.) I recall endless drills regarding the differences of homonyms like to, too and two. HAlloween is not hollow. FebRuary isn't Feb-you-ary. PuMPkin has only one N. I could write for hours about all the mispronunciations and grammar mistakes I am forced to suffer every day. I am an ISTJ Aspie and poor English is a constant, painful irritation to me. I am grammar witch!
