When Does the Stupidness Stops

I am a little pissed today. Last night, I came home with 6 kids. 4 that aren't mine. I don't understand how parents can be so damn stoopid, not stupid. Here's the scenario. This couple has 4 kids. The oldest is 16 and pregnant. They are living in a hotel. The oldest sleeps on the floor and the three share a bed. The parents decided to invite a friend and his girlfried to stay the night. How in the hell can you invite someone over when you don't even have room for you and your family?!? The next to the oldest and my daughter kept calling to see if they could stay at my house because there wasn't enough room and they felt uncomfortable with the guy being there. The whole time I was saying that isn't my problem. I never, not once, heard from either of the parents. In the back of my mind, I can't help but think the parents put the kids up to this so they can go out and party. I told them before I came home that I wasn't going to grocery to get any groceries and I didn't want to hear any noise from any of them. I have never been so livid in my life. This is just ridiculous. From now on, there will not be anymore incidents like this. It's time to put my foot down and in someone's tail if I need to. I have the right to call and report this to CPS.
