I've been called hard work too as I seemingly never listen to a word anyone says to me. But it's not irreverence on my part; I am just terrible at recalling auditory information. As well as autism, I wouldn't be surprised if I have a CAPD and an inattentive subtype of ADHD. Even when I am not depressed (I think I am at the moment as few things seem to excite me), I can seem as if I am "away with the fairies". I have, on many occasions, be accused of being stoned, when in fact I was stone cold sober. I never really seem 'with it'.
