Memes, you're a mom so you already know how this goes with kids and fights. Same sort of deal. You have to deal with the issue and seperate it from the adults and them losing their ever lovin' minds. If friend #1 (the idiot dog owner) keeps stuffing her nose into your relationship with friend #2 you have even more reason to turf her out of your life. Geesh with friends like that, who needs enemies.
