DD has some friends down the street who she likes playing with, she is 9. One of the girls is 14 (IMO way too old for her to be playing with) and the other is 12. These girls are homeschooled (which I'm all for) unfortunately their parents are never home and according to DD, they never do schoolwork. They stay home by themselves until 7-8 pm. They are constantly coming over inviting themselves to play, eat dinner, stay the night, etc. I don't ever allow DD to go to their house because the parents are never there, and even if they were I still wouldn't let her. They are ALWAYS here. I feel really bad for them, but also sort of don't want them hanging out with DD. Should I allow them to keep hanging out and playing or tell DD no more of these friends?
