I was really surprised by the response to the second letter about the person who keeps being questioned about their assistance dog - disabled people have a right to privacy and to be seen as people rather than being defined by 'what they can't do'. I don't see those sort of questions from complete strangers as being curious, I find them rude and offensive (from adults, I don't mind from kids). It's different when you are getting to know someone, of course you'll both ask questions but I've been quizzed in the street by complete strangers about my son's disability and it's terribly invasive. I wouldn't march up to someone and ask for information about their toilet habits or their sex lives, why should people be expected to give out personal information about their health to people they don't know?
I agree. It's just as invasive to walk up to a pregnant woman and grab her belly without permission! Sheesh!
When I've encountered others with service animals, I usually comment that their Fur-Baby is GORGEOUS....and they always are!

(Can you tell I love animals?) We then talk about their Fur-children, their names, how old they are, and I always ask permission, first, if I can say 'hello' to the Fur-Baby too. By then, we're usually seated and yakking away and sharing about mutual challenges that we have in common. I often imagine how I would feel if someone, a total stranger, walked up to me and invaded my space without permission. It would NOT be pretty!
