Looking at the ex and my own excursions outside the inner city with DS I'd agree. How the hell am I supposed to teach DS basic social courtesy whn every other word uttered by the the adults on the bus or at the corner shop is a swear word?
I've purposely cultvated a few "golden oldies" that we've met walking the dog to enalee DS to practise simple greetings like "How are you today", (no he doesn't get why he should respond "fine" yet but I live in hope lol!). Please and thank you is another basic, basic courtesy that he's deffo learnt from a good nursery/the old dears. He prefers it in places like Wales as he knows what's expected of him and people answer as he expects when he tries to be social(e.g good morning, instead of a grunt)
It's a key reason why I strongly feel relocating would be beneficial for him in the long run. He NEEDS good general role models, family and friends aren't enough if we are constantly contradicted by the ijeets on the the streets daily iykwim. (random person at bus stop, a TA that doesn't drop every H in sight aka Amy Childs etc).
I also feel very strongly that havng had pets from an early age (our dog isa total sweetie pie) has helped his empathy develop> His AS dad feels the same even if neither of us can put our fingers on exactly WHY in a scientific way. A dog is totally non-verbal yet they let you know how they are feeling, perhaps it's the very simple nature of the interaction that kick starts a brain synapse or two?
His Dad doesn't "get" a lot of "people stuff" - it has to be pointed out to him in words of one syallable but he understands violence is wrong. A zero tolerance approach was how he was taught from babyhood and I've done the same with my lad.
