It was a throwaway comment; nothing more, nothing less so it doesn't make me feel better or worse. I actually used to be a teacher at a dyslexic school so when I saw 'disfunctional', it stood out to me as I was so used to seeing the word 'dyslexic'. For the record, when I type in 'dislexic' and 'disfunctional' both words are underlined, once again highlighting the mistake to me.
