Often times, My SD makes a confused face, which is usually followed by a smartass comment. She pretends to act confused because she is under the assumption if she does she will be excused from being a smartass. This is akin to the "do something wrong and then act innocent afterwards like I didn't know it was wrong". Please keep this in mind for the following conversation:

Me: okay SD. We are about to go to the mall and go to Macys. I am going to give you 15$ to spend on a present for your mother. You can spend that AND bring your money that you earned doing chores in case you see a present and want to go over that amount. Okay?
SD: but...what? That makes no sense. My mom bought you several gifts.
Me: you can choose several gifts. It doesn't have to be one gift. You can go over fifteen dollars, but you have to use your allowance money for the rest.
SD makes her confused face:
My mom spent more than 15$ on you. Isn't that embarassing for you?

BOOM. I KNEW this would turn into some kind of pissing contest. SD does this. Tries to get hex and I to outdo the other. I did not know how to respond to this. Honestly, if my kid said that to me I would go off on her.

Me: SD, it is not the amount of money nor the amount of gifts that matters. You can spend a hundred dollars or buy a hundred gifts, but If it has no meaning than it is worthless. This is about YOU getting your mom a nice gift. It is not about her or I. If you are unhappy with the amount, you can just color her something instead.

SD: okay. Just know that my mom spent 40$ on you.

At the mall, SD beelines straight to the jewelry counter. She asks the clerk for emeralds, bc her mom loves those. I redirect her to the cheaper, on sale jewelry. Macys has some great sales-60% off! SD grimaces, and says her mom only likes x brand. Whatever kid. SD then says she knows her moms shirt size, and wanders towards women's shirts. She peruses for the longest time, glancing at everything. And then she finds it: the perfect gift- a black shirt.

She proudly hands it to me. A plain, black shirt. Her mother LOVES black. With ugg boots. It's the signature look, SD informs me. I tell her it is beautiful, and her mother will appreciate it. SD is happy. Yayyyy for the 14$ black shirt!
But the more I think about this, the more annoyed I get. She has NO concept of money. Yet I enabled her-I allowed her to pick out a gift. And hex will inevitably ask SD how much it cost, to which some snooty conversation will occur.

Whatever. Enjoy the shirt hex. It will go well with your pitchfork.
