Beebs....I didn't understand your response. Sure they are that person's children, however, that's part of the problems in society today...everyone turns a blind eye and don't want to get involved. You say your peace and if they don't want to listen or understand then you move on, of course, but now that seed is planted and they might think about it. To me it's similar albeit less dramatic than physical abuse but they are harming that child physically. I love my mom but I dislike how she raised me to eat...everything better with sugar and sauce. lol
Perhaps a more gentle approach toward the parent would be better received and make them more receptive than putting them on the defensive. It's all in the delivery...watch Doug...he's a master at talking to people...he talks logic and facts and logic/facts are difficult to dispute. When it turns to emotional pleas the battle is lost.
Anyway....I think I am getting off track and need to get down off my soap box. lol
