Never go shopping with another kid not your own

Yesterday, I wanted to pull my hair out, Droopy's hair, and Whinis' hair out. Seriously Stinky does not behave well around Whinis. He reverts to a more juvenile self. It was not fun shopping at the market with Droopy and kid. Droopy was all excited about being there. Fine, whatever you know it's gonna be a bad trip when the kid is sitting on refrigerator cases, and his mother is not even paying attention. This was when we first got in for lunch. I was going nuts. She's exploring the store, he's exploring the store, and neither one is thinking about where the other one was. Whinis, is loud, and short tempered. I'm glad Droopy knows that about her kid. But she wasn't controlling him. He was being very argumentative with Stinky. Stinky was letting him win in the egging contest. It was not good. Stinky and I don't have this problem. He may get bored, but he stays close by and I'm on him at all times. Mean, evil mom at work, and all that. I had to pull the two aside and tear them new ones, several times. I was literally ready to pull both kids out and lock them in the car. Or just leave Whinis and Droopy to fend for themselves. Whinis sat on beer cases! He literally climbed a stack of Heineken's and sat on them! Droopy was right there! I had yelled at him in front of his mother, and she ignored it. Not good. I don't want to babysit her kid, while she has fun. If the opportunity ever arises like that again, I will have no problems telling her no. I'm driving my kid is coming. Yours can stay at home or with a babysitter. I'm not watching out for your kid, and all the boys did was argue with each other. So irritating having to play babysitter, and not get any help.
