@BoredStupid I think people with level 1 struggle very much with communication and it is a huge handicap. They can get better at it through intense training and effort (sometimes), but it is never natural for them. Subtle cues, humor, sarcasm, innuendo, etc. just go whoosh. My dogs and I communicate better than many people with ASD can with other people. Agree with you about the vaccines. Most kids begin speaking and then regress (like my daughter) after a round of them.
