The neighbourhood hang out

My home has become the neighbourhood hang out for all of the kids. I think this has happened for a couple of different reason. 1) I have the most kids in the complex so it is easier to just have other kids over here then send all of my kids over to another house and have then destroy that home too. 2) Half of the kids live with single mothers and Jason has become the "dad" to most of them and even call him dad at times too. 3) I have a big fat "I don't care" tattoo on my face so the kids get away with almost anything. (no illegal or dangerous activity better be going on in my home and if I find out it happens you are done.)

So as such of a result of such reasons my home has also become the place where working mothers send their kids after school to make sure that homework gets done and a snack is served and the child is kept safe (LOL safe in my house, that is so funny). Well I really wish that I was not such a nice person and said "Um, you realize that I only have my kids Monday, Thursday and every other Friday? Meaning I really would rather not be watching your kids for free on the days when my kids are not here because I do enjoy the peace and quiet too." I also have this problem with the fact that in a few weeks there will be this new creature living in our home called a baby. It would be nice if I did not have my house filled with germs while my little one is still so little. How do I nicely tell my neighbours "go find another schmuck to dump your kids on"?
