It's the same in our surgery, but the town has expanded a lot recently and there aren't enough parking spaces for all the residents of the estates further than walking distance from the centre, so I suspect a few are parkers rather than patients.
Back to GP's BCD - I am always surprised at how many people take friends and family into appointments with them. Obviously parents will accompany children, and elderly people might want a son or daughter as another pair of ears, but there are husbands and wives, siblings and all sorts of combinations of what appear to be capable people going in together.
My son is 35 and autistic, although you can’t tell in casual observation. I always ask if he wants me to go in and he always says yes. Sometimes I think that the medic looks a bit surprised but after a few questions they get it. My son struggles to understand questions if they aren’t presented in a very straightforward way and has issues with paying attention. He often can’t answer questions because he isn’t able to think clearly about what his issues are. Lastly he can’t remember what advice he is given, because he finds it so hard to pay attention.
