So, you are playing with your kids in the park in an urban area. You look around you and see the scene depicted in the above picture. (This picture depicts the third floor of an apartment building).
What do you do? Do you yell up to the kids to get back inside? Do you gather up your own children and go hammer on the apartment door to see if there is an adult there and if said adult is aware that there are children dangerously hanging out of a window? Do you call Child Protective Services? Or do you just move on?
