Outside pet store. Dog is trying to leap off a curb toward our car. We stop her and ask her to sit. She is tired and hasn't even had lunch yet, so is reluctant to sit. We say SIT and she finally sits.
Random lady walks by and says "Don't forget to praise them when they do what you say or else they won't do it next time."
Oh okay thanks lady. Because I've done ZERO research on dogs and dog training. And also, because we asked for your assistance. Move on with your day.
