I've seen quite a few posts where people are saying that Hugo has Aspergers. I personally don't think he has ASD, I just think he's been constantly babied and had his boundaries continually invaded that he doesn't realise that any of this isn't 'normal'.
Having an 18 year old Aspie son myself, I just don't see any of the traits in Hoggy - but none of us on the internet could (or should even try to) diagnose someone as being on the spectrum, or even speculate about it. It's thrown around in society as a buzz word when someone appears a "bit weird" or "awkward" and it's so damaging to the ASD community.
