The people _never_ ask if my dog on her 2 meter leash (the law in Arizona, btw) is friendly, dangerous, anything. They just announce that their dog isn't dangerous to us.
So often the small dog runs up to my dog's face full speed, centimeter from her nose, gets satan-barked at and driven away from us. she's sensibly trying to protect me and her from the little barely tethered full speed maniac.
The people ask if my dog was abused. Nope: had her since she was three months old, the feral mom and others were all adopted. They just don't seem to consider that _they_ were aggressive, in dog body language. And that's hopefully eye opening for them.
