Teen's mood swings are messing up my day.

So I am starting to hate when my teens have mood swings. The way they arch there back and drag there feet, and move slower then heck around the house is rather annoying. They come home, and it takes them two sim hours to get from the front door to do the homework, and then another three to eat. Forget it, I am like do your homework and go to bed stinky, hungry, and with a full bladder because it will take you two days just to get all that done. I failed a birthday party because of the mood swing they took forever to get to the cake to blow out the candles and the event ended before they got there.
