Worn OUT

So today was the day I was absolutely DREADING. My sister dropped off Isaiah at 1:00, then left for work. At 2:15, I loaded up all the kids and drove the 30 minutes to Wimberley, got in the line outside the school and waited and waited...I finally got Isabella in the car and headed away form the school at 3:20, then headed to Wal-Mart in San Marcos to get a few items. I ended up buying a bag of chips for the kids...mainly because they wouldn't shut up about being hungry. I can see why my sister can't save enough money to get out on her own...her kids never stop eating. Seriously, the month that I was at my parents house I was so irritated at the kids eating habits. They eat junk food ALL day long and barely eat their dinner. As soon as Isabella gets home from school she eats two bowls of cereal, and not cheerios or some sort of healthy cereal, the sugary kind. Then there is usually the large bag of chips that her and Isaiah share and lets not forget all the candy that is stashed all over that house. I seriously dont see how they aren't extremely overweight, it sickens me to think about how much they eat...oh and drink, I mean seriously, it is soda after soda after soda. So we finally get back to my house, and they go out to play after eating the entire bag of chips in less than 5 minutes. I told Isabella she needs to take a larger lunch if she is that hungry after school. I mean I understand an afternoon snack, but come on. Anyway, they play outside, which is great for me, because I was just trying to relax a bit and nurse my horrible headache. Then started the in and out...I quickly put that to a stop. They just came inside and I instructed Isabella to get out her homework, which was followed by an arguement because she didn't think she needed to do it right then. Ughhh....can they not see that I am in a bad mood! I am so pissed. I dont want to this anymore. Next week, no matter what, when my sister TELLS me which day I will be watching the kids, I will be making up some other plans. I am not doing it. I need a week off...I need a week of being with MY family. I am so tired...4 kids really drain me.
